* powerpc64le: Fix TFtype in sqrtf128 when using -mabi=ieeelongdoubleTulio Magno Quites Machado Filho2018-06-061-3/+8
| | | | | | | | | | | | | | | | When building with -mlong-double-128 or -mabi=ibmlongdouble, TFtype represents the IBM 128-bit extended floating point type, while KFtype represents the IEEE 128-bit floating point type. The soft float implementation of e_sqrtf128 had to redefine TFtype and TF in order to workaround this issue. However, this behavior changes when -mabi=ieeelongdouble is used and the macros are not necessary. * sysdeps/powerpc/powerpc64/le/fpu/e_sqrtf128.c [__HAVE_FLOAT128_UNLIKE_LDBL] (TFtype, TF): Restrict TFtype and TF redirection to KFtype and KF only when the default long double type is not the IEEE 128-bit floating point type.

* powerpc: Add multiarch sqrtf128 for ppc64leRajalakshmi Srinivasaraghavan2018-05-304-0/+107
| | | | | | | This patch creates ifunc for sqrtf128() to make use of new xssqrtqp instruction for POWER9 when --enable-multi-arch and --with-cpu=power8 options are used on power9 system. This is achieved by explicitly adding -mcpu=power9 flag for sqrtf128-power9.
* powerpc: Move around math-related ImpliesTulio Magno Quites Machado Filho2018-05-242-0/+10
| | | | | | | | | | | | | | | Currently, powerpc, powerpc64, and powerpc64le imply the same set of subdirectories from sysdeps/ieee754: flt-32, dbl-64, ldbl-128ibm, and ldbl-opt. In preparation for the transition of the long double format - from IBM Extended Precision to IEEE 754 128-bits floating-point - on powerpc64le, this patch splits the shared Implies file into three separate files (one for each of the powerpc architectures), without changing their contents. Future patches will modify powerpc64le. * sysdeps/powerpc/Implies: Removed. Previous contents copied to... * sysdeps/powerpc/powerpc32/Implies-after: ... here. * sysdeps/powerpc/powerpc64/be/Implies-after: ... here. * sysdeps/powerpc/powerpc64/le/Implies-before: ... and here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The creation of the divergent sysdeps directory for powerpc64le commit 2f7f3cd8cd302bb10908c86f3f7b349df0a78e6a Author: Paul E. Murphy <murphyp@linux.vnet.ibm.com> Date: Fri Jul 15 18:04:40 2016 -0500 powerpc64le: Create divergent sysdep directory for powerpc64le. allowed float128 to be enabled for powerpc64le (little-endian) and not for powerpc64 (big-endian). Since the only intended difference between them was the presence or absence of the float128 interface, the sysdeps directory for powerpc64le explicitly reused the files from powerpc64 (through the use of Implies files). Although this works, it also means that files under the powerpc64 directory might be preferred over files under powerpc64le. For instance, on a build for powerpc64le with target set to power9, a file from powerpc64/power5 might get built, even though a file with the same name exists in powerpc64le/power8. That happens because the processor hierarchy was only defined in the sysdeps directory for powerpc64 (and borrowed by powerpc64le). This patch fixes this behavior, by creating new subdirectories under powerpc64 (i.e.: powerpc64/be and powerpc64/le) and creating new Implies files to provide the hierarchy of processors for powerpc64 and powerpc64le separately. These changes have no effect on installed, stripped binaries (which remain unchanged). Tested that installed stripped binaries are unchanged and that there are no regressions on powerpc64 and powerpc64le.
* elf: Unify symbol address run-time calculation [BZ #19818]Maciej W. Rozycki2018-04-041-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.

* Define powerpc64 lroundl compat symbol only once.Joseph Myers2017-12-011-1/+0
| | | | | | | | | | | | | | | sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c defines the lroundl compat symbol, version GLIBC_2_1, twice, once based on llround and once based on __lround. Those are aliases for each other (llround weak, __lround strong), but defining it twice does not make sense. This patch changes it to define the compat symbol once only, matching how libm_alias_double defines it. Tested with build-many-glibcs.py for its powerpc64 configurations. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c [LONG_DOUBLE_COMPAT(libm, GLIBC_2_1)] (lroundl): Do not define compat symbol based on llround.
* Base powerpc logbl compat symbols on __logb not logb.Joseph Myers2017-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | Some powerpc logb implementations define a compat symbol for logbl based on logb, whereas libm_alias_double defines such a compat symbol based on __logb instead. This difference (logb is weak, __logb isn't) is enough to result in different installed stripped shared libraries. The difference in the installed libraries isn't significant, but first changing the compat_symbol calls helps make it possible to validate a subsequent change to use libm_alias_double by comparison of libraries, so this patch does such a preliminary change. Tested with build-many-glibcs.py for all its hard-float powerpc configurations. * sysdeps/powerpc/power7/fpu/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Define as compat symbol based on __logb, not on logb. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise.

This brings in automatic symbol versioning compat handling, so the powerpc32 and powerpc64 wrappers that added such handling to the generic sysdeps/powerpc/fpu versions are removed as no longer required (there are no sysdeps directory ordering issues that would necessitate keeping trivial wrappers there). Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged for all its hard-float powerpc configurations. * sysdeps/powerpc/fpu/s_fabs.S: Include <libm-alias-double.h>. (fabs): Define using libm_alias_double. * sysdeps/powerpc/fpu/s_fma.S: Include <libm-alias-double.h>.

* PowerPC64 power8 strncpy cfi fixesAlan Modra2017-10-231-13/+14
| | | | | | | | | | | | | | | | | | | | | cfi info for stack adjust needs to be on the insn doing the adjust. cfi describing register saves can be anywhere after the save insn but before the reg is altered. Fewer locations with cfi result in smaller cfi programs and possibly slightly faster exception handling. Thus the LR cfi_offset move. The idea behind ajusting sp after restoring regs is to break a register dependency chain, in this case not be using r1 immediately after it is modified. The missing LR cfi_restore meant that code after the blr, unaligned_lt_16 and other labels, would have cfi that said LR was at cfa+16, but that code is reached without LR being saved. * sysdeps/powerpc/powerpc64/power8/strncpy.S: Move LR cfi.

* powerpc: Add redirection for finitef128, isinf128, and isnanf128Gabriel F. T. Gomes2017-09-213-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On powerpc64le, compiler support for float128 is not enabled by default on gcc. To enable it, the flag -mfloat128 must be passed as a command line option to the compiler. This means that only the few files that actively have -mfloat128 passed as an argument get compiler support for float128, whereas all other files don't. When -mfloat128 becomes enabled by default on powerpc [1], all the files that do not currently have compiler support for float128 enabled during their compilation, will start to have it. This will lead to build errors in s_finite.c, s_isinf.c, and s_isnan.c. The errors are due to the unintended macro expansion of __finitef128 to __redirect_finitef128 in math/bits/mathcalls-helper-functions.h. In that header, __MATHDECL_1 takes '__finite' and 'f128' as arguments and concatenates them. However, since '__finite' has been redefined in s_finite.c, the function declaration becomes __redirect_finitef128: extern int __redirect___finitef128 (_Float128 __value) __attribute__ ((__nothrow__ )) __attribute__ ((__const__)); This declaration itself is OK. The problem arises when include/math.h creates the hidden prototype ('hidden_proto (__finitef128)'), which expands to: extern __typeof (__finitef128) __finitef128 __attribute__ ((visibility ("hidden"))); Since __finitef128 is not declared, __typeof fails. This effect was already true for the 'float' and 'long double' versions and is now true for float128. Likewise for isinsff128 and isnanf128. This patch defines __finitef128 as __redirect___finitef128 in sysdeps/powerpc/powerpc64/fpu/multiarch/s_finite.c, similarly to what's done for the float and long double versions of these functions, to get rid of the build error. Likewise for isinff128 and isnanf128.

Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

* tst-tlsopt-powerpc as a shared libAlan Modra2017-08-031-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the __tls_get_addr_opt test run as a shared library, and so actually test that DTPMOD64/DTPREL64 pairs are processed by ld.so to support the __tls_get_adfr_opt call stub fast return. After a 2017-01-24 patch (binutils f0158f4416) ld.bfd no longer emitted unnecessary dynamic relocations against local thread variables, instead setting up the __tls_index GOT entries for the call stub fast return. This meant tst-tlsopt-powerpc passed but did not check ld.so relocation support. After a 2017-07-16 patch (binutils 676ee2b5fa) ld.bfd no longer set up the __tls_index GOT entries for the call stub fast return, and tst-tlsopt-powerpc failed. Compiling mod-tlsopt-powerpc.c with -DSHARED exposed a bug in powerpc64/tls-macros.h, which defines a __TLS_GET_ADDR macro that clashes with one defined in dl-tls.h. The tls-macros.h version is only used in that file, so delete it and expand. * sysdeps/powerpc/mod-tlsopt-powerpc.c: Extract from tst-tlsopt-powerpc.c with function name change and no test harness. * sysdeps/powerpc/tst-tlsopt-powerpc.c: Remove body of test.

* Rename struct ucontext tag (bug 21457).Joseph Myers2017-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed. Tested for x86_64, and with build-many-glibcs.py.
