| | | | | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 4.15. There only appears to be one new syscall to add to the list. (The riscv_flush_icache syscall is *not* added because for whatever reason it doesn't appear in the uapi asm/unistd.h; only in arch/riscv/include/uapi/asm/syscalls.h, which is only included by the non-uapi asm/unistd.h - and only syscalls whose __NR_* macros are defined in the uapi asm/unistd.h are relevant for this list.)

* Move LDBL_CLASSIFY_COMPAT to its own header.Joseph Myers2018-02-0116-30/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The general rule in glibc is that it's better for a macro to be always defined, and tested with #if, than for it to be tested with #ifdef, because the latter is prone to typos in the macro name as well as to the header with the macro accidentally not being included in a file testing it. (Testing with an "if" statement is even better, in those cases where it's possible to do things that way, as it then means both cases in the code get checked for syntax in glibc builds with either value of the condition.) math_private.h has several different groups of macros, meaning that architectures wanting to override some of them need to define those then include the generic version, which then defines macros if not already defined. It's hard to avoid that arrangement completely, but various cases can be improved by splitting out macros or groups of macros into separate files. This patch splits out the LDBL_CLASSIFY_COMPAT macro into a separate ldbl-classify-compat.h header. This macro is tested with #ifdef; this patch changes it to testing with #if, with a default definition to 0 in the generic header and then architecture-specific headers defining it to 1.

* Remove some math_private.h libc_feholdexcept_setround overrides.Joseph Myers2018-02-016-106/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | math_private.h headers for configurations lacking support for floating-point exceptions and rounding modes define libc_feholdexcept_setround to override the default version with one that discards its rounding mode argument. Unlike other such libc_fe* macros that I removed, this one is actually used for such configurations (in dbl-64/e_sqrt.c). However, this does not make the macro required. It's only used for such configurations with FE_TONEAREST as the rounding mode (anything needing another mode should not be used when that mode is unavailable), and the default definition just calls __feholdexcept and __fesetround. Since we now have suitable inline do-nothing definitions of __feholdexcept and __fesetround for the cases of no exceptions and rounding modes, we can just rely on those inlines to achieve the same optimization as this macro definition. Thus, this patch removes those macro definitions (and the math_private.h headers containing them, when no longer needed after that removal). Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/m68k/coldfire/fpu/math_private.h: Move to .... * sysdeps/m68k/coldfire/math_private.h: ... here. * sysdeps/m68k/coldfire/nofpu/math_private.h: Remove file. * sysdeps/tile/math_private.h: Likewise. * sysdeps/microblaze/math_private.h (libc_feholdexcept_setround): Remove macro. * sysdeps/nios2/math_private.h (libc_feholdexcept_setround): Likewise.
* Remove some math_private.h libc_fe* overrides.Joseph Myers2018-02-015-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | math_private.h headers for configurations lacking support for floating-point exceptions and rounding modes define various libc_fe* macros to override the default versions with ones that discard any exception or rounding mode arguments. Three of the four macros defined in these headers are no longer needed there: those macros are only used in fma implementations that are not used for such configurations, now all those configurations properly use soft-fp fma implementations instead. (Effectively, those macros were a workaround to allow glibc to build in the absence of a proper fma implementation for this case - now there is such an implementation, there is no need to support building the wrong implementation for those configurations.) Thus, this patch removes the unnecessary macros.

* Add feholdexcept inline in generic math_private.h.Joseph Myers2018-02-012-0/+18
| | | | | | | | | | | | | | | | | | | | | Continuing the process of improving and cleaning up the handling of configurations lacking support for floating-point exceptions and rounding modes, this patch adds trivial inline definitions of feholdexcept and __feholdexcept to the set of inlines for such configurations in math_private.h. These inlines were missing from the tile version used as a basis for the previous inlines, despite a few such function calls ending up in libm.so. Tested with build-many-glibcs.py. As expected, installed stripped shared libraries are unchanged for architectures supporting exceptions and rounding modes, but changed for architectures lacking such support. * sysdeps/generic/math_private.h [!FE_HAVE_ROUNDING_MODES && FE_ALL_EXCEPT == 0] (feholdexcept): New inline function.

* Move fenv.h override inline functions to generic math_private.h.Joseph Myers2018-02-014-14/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tile version of math_private.h defines some inline functions for fenv.h functions, to optimize away internal calls to these functions that do nothing given no support for floating-point exceptions and rounding modes. (Some functions may have error cases for invalid arguments, but those aren't applicable to the internal calls from within glibc.) Other configurations lacking support for exceptions and rounding modes lack such inline functions. This patch moves them to the generic math_private.h, appropriately conditioned, so that all such configurations can benefit from the. include/fenv.h is made to check whether there are any non-default rounding modes; that needs to be done there, rather than later, because get-rounding-mode.h defines values for otherwise unsupported FE_* rounding modes. It also gives an error for FE_TONEAREST undefined, a case that already did not work for building the glibc testsuite; the convention has by now been established that all architectures need to provide a version of bits/fenv.h that at least defines FE_TONEAREST. Tested with build-many-glibcs.py. As expected, installed stripped shared libraries are unchanged for tile and for architectures supporting exceptions and rounding modes, but changed for non-tile architectures not supporting exceptions and rounding modes that previously lacked this optimization (e.g. Nios II libm.so is about 1kB smaller). The optimization is not in fact complete (does not cover feholdexcept / __feholdexcept, so a few calls to those remain unnecessarily within libm even after this patch), but that can be dealt with separately. * include/fenv.h [!_ISOMAC && !FE_TONEAREST]: Give #error.

* Move some fenv.h override macros to generic math_private.h.Joseph Myers2018-02-016-25/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various configurations lacking support for floating-point exceptions and rounding modes have a math_private.h that overrides certain functions and macros, internal and external, to avoid references to FE_* constants that are undefined in those configurations. For example, there are unconditional feraiseexcept (FE_INVALID) calls in generic libm code, and these macro definitions duly define feraiseexcept to ignore its argument to avoid an error from FE_INVALID being undefined. In fact it is easy to tell in an architecture-independent way whether this is needed, by testing whether FE_ALL_EXCEPT == 0. Thus, this patch puts such a test, and feraiseexcept and __feraiseexcept macros, in the generic math_private.h, so reducing the duplication between architecture versions of this header. The feclearexcept macro present in several versions of this header, and fetestexcept in the tile version, are not needed; they would have been needed before there were proper soft-fp fma implementations (when generic versions, that depend on FE_TOWARDZERO and FE_INEXACT, were being used for configurations not supporting those features), but aren't needed any more, and so are removed. The tile version of this header has several inline functions for fenv.h functions to optimize calls to them away in such configurations where they do nothing useful, and all these header versions also have definitions of some of the libc_fe* internal macros. I intend to make those generic in subsequent patches. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/math_private.h [FE_ALL_EXCEPT == 0] (feraiseexcept): New macro.

* Add ColdFire math-tests.h.Joseph Myers2018-02-012-0/+31
| | | | | | | | | | Since I've been fixing build issues for ColdFire, this patch adds a math-tests.h file for ColdFire, reflecting the lack of support for exceptions and rounding modes for soft float. I think it is logically correct, but have not tested it beyond build-many-glibcs.py for both hard and soft float. * sysdeps/m68k/coldfire/math-tests.h: New file.
* Fix m68k bits/fenv.h for no-FPU ColdFire.Joseph Myers2018-02-012-11/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The m68k bits/fenv.h is in sysdeps/m68k/fpu/, meaning that no-FPU ColdFire instead gets the generic (top-level) bits/fenv.h. That top-level bits/fenv.h defines no rounding mode constants. That no longer works for building glibc tests: some tests fail to build (at least with warnings) if no rounding mode macros are defined, so at least FE_TONEAREST must be defined in all cases (as various architectures without rounding mode support indeed do), while __FE_UNDEFINED must be defined in the case where not all the standard rounding modes are supported. On general principles of supporting multilib toolchains with a single set of headers shared between multilibs for a given architecture, it's also desirable for the same bits/fenv.h header to work for both FPU and no-FPU configurations. Thus, this patch moves the m68k bits/fenv.h to sysdeps/m68k/bits/fenv.h, and inserts appropriate conditionals to handle the no-FPU case. All the exception macros, and FE_NOMASK_ENV, are disabled in the no-FPU case; FE_ALL_EXCEPT is defined to 0 in that case. All rounding modes except FE_TONEAREST are disabled in that case, and __FE_UNDEFINED is defined accordingly. To avoid an unnecessary ABI change, fenv_t is defined in the no-FPU case to match the definition it would have got from the generic bits/fenv.h. This suffices to get a clean glibc and testsuite build for this configuration with build-many-glibcs.py (and keeps a clean build for the other m68k configurations); it has not been otherwise tested. * sysdeps/m68k/fpu/bits/fenv.h: Move to .... * sysdeps/m68k/bits/fenv.h: ... here.

* Do not use packed structures in soft-fp.Joseph Myers2018-02-016-6/+15

But with the form used in this code struct { ... } bits __attribute__ ((packed)); the field bits is being declared packed, but the layout of its type has already been determined at that point. If on any platform the layout of the sequence of bit-fields were wrong without the use of a packed attribute, the attribute would need to be used via a definition of _FP_STRUCT_LAYOUT, not in its present position. So this patch removes the useless attribute to fix the build for ColdFire soft-float.

* RISC-V: Build InfastructurePalmer Dabbelt2018-01-2919-0/+451
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch lays out the top-level orginazition of the RISC-V port. It contains all the Implies files as well as various other fragments of build infastructure for the RISC-V port. This contains the only change to a shared file: config.h.in. RISC-V is a family of base ISAs with optional extensions. The base ISAs are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but this port currently only supports RV64I based systems. Support for RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc port supports most of the currently-defined extensions: the A extension for atomics, the M extension for multiplication, the C extension for compressed instructions, and the F/D extensions for single/double precision IEEE floating-point. Most of these extensions are handled by GCC, but glibc defines various floating-point wrappers and emulation routines as well as some atomic wrappers. We support running glibc-based programs on Linux, the support for which lives in sysdeps/unix/sysv/linux/riscv. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/Implies: New file. * sysdeps/riscv/Makefile: Likewise. * sysdeps/riscv/configure: Likewise. * sysdeps/riscv/configure.ac: Likewise. * sysdeps/riscv/nptl/Makefile: Likewise. * sysdeps/riscv/preconfigure: Likewise. * sysdeps/riscv/rv64/Implies-after: Likewise. * sysdeps/riscv/rv64/rvd/Implies: Likewise. * sysdeps/riscv/rv64/rvf/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/Versions: Likewise. * sysdeps/unix/sysv/linux/riscv/configure: Likewise. * sysdeps/unix/sysv/linux/riscv/configure.ac: Likewise. * sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/shlib-versions: Likewise.
