* [powerpc] add 'volatile' to asmPaul A. Clarke2019-06-192-5/+5
| | | | | | | | | | | | | | Add 'volatile' keyword to a few asm statements, to force the compiler to generate the instructions therein. Some instances were implicitly volatile, but adding keyword for consistency. 2019-06-19 Paul A. Clarke <pc@us.ibm.com> * sysdeps/powerpc/fpu/fenv_libc.h (relax_fenv_state): Add 'volatile'. * sysdeps/powerpc/fpu/fpu_control.h (__FPU_MFFS): Likewise. (__FPU_MFFSL): Likewise. (_FPU_SETCW): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC always expand copysign{f} for all possible cpus, so calling the libm is only done if user explicitly states to disable the builtin (which is done usually not for performance reason). So to provide ifunc variant for copysign is just unrequired complexity, since libm will be called on non-performance critical code. This patch removes both powerpc32 and powerpc64 ifunc variants and consolidates the powerpc implementation on sysdeps/powerpc/fpu/s_copysign{f}.c using compiler builtins. Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+ and --disable-multi-arch). * sysdeps/powerpc/fpu/s_copysign.c: New file. * sysdeps/powerpc/fpu/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc32/fpu/s_copysign.S: Remove file. * sysdeps/powerpc/powerpc32/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/Makefile (sysdep_routines, libm-sysdep_routines): Remove s_copysign-power6 and s_copysign-ppc32. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-power6.S: Remove file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-ppc32.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile (sysdeps_calls): Remove s_copysign-power6 s_copysign-ppc64. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-power6.S: Remove file. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc64/power6/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc64/power6/fpu/s_copysignf.S: Likewise.

For example, when a POWER6 instruction is used, but '.machine power6' is not declared, the assembler will fail with an error similar to the following: ../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages: 24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb' This patch adds '.machine powerN' directives where none existed, as well as it updates '.machine power7' directives on POWER8 files, because the minimum binutils version required to build glibc (binutils 2.25) now provides this machine version. It also adds '-many' to the assembler command used to build tst-set_ppr.c. Tested for powerpc, powerpc64, and powerpc64le, as well as with build-many-glibcs.py for powerpc targets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 9 dropped support for the SPE extensions to PowerPC, which means powerpc*-*-*gnuspe* configurations are no longer buildable with that compiler.

* powerpc64le: Remove test for GCC 6.2Gabriel F. T. Gomes2019-02-202-69/+1
| | | | | | | | | | | | | | | | | | | | | | The configure fragment for powerpc64le contains a test for the presence of several compiler builtins and of the __float128 type, which are provided by GCC 6.2 for powerpc64le. Since this configure test was added, the compiler version required to build glibc for powerpc64le was different than that required for the other architectures. Now that glibc requires GCC 6.2 globally (since commit ID 4dcbbc3b28aa), this patch removes the powerpc64le-specific test. Even tough the configure test checks for compiler features rather than compiler version, the intent of the test was to stop build attempts at early stages, if they had been configured with a too old compiler. It was not the intention of the test to detect compiler breakage (such as the removal of the required compiler features in future GCC versions), and glibc is not the place to test for compiler regressions, anyway. Tested for powerpc64le with GCC 6.2 (built with build-many-glibcs.py). Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>

* Add hidden_tls_def macros, fix powerpc-soft build with GCC 9.Joseph Myers2018-11-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Soft-float powerpc fails to build with current GCC mainline because of use of libc_hidden_data_def for TLS variables, resulting in a non-TLS alias being defined, to which the tls_model attribute is now copied, resulting in a warning about it being ignored. The problem here appears to be the non-TLS alias. This patch adds a hidden_tls_def macro family, corresponding to the hidden_tls_proto macros, to define TLS aliases properly in such a case, and uses it for those powerpc soft-float variables. Tested with build-many-glibcs.py compilers build for powerpc-linux-gnu soft-float.

Furthermore, since the optimized inlines of various functions have been moved to include/fenv.h or replaced by use of function names GCC inlines automatically, a missing math_private.h include where one is appropriate will reliably cause a build failure rather than possibly causing code to be less well optimized while still building successfully. Thus, this patch removes includes of math_private.h that are now unnecessary. In the case of two RISC-V files, the include is replaced by one of stdbool.h because the files in question were relying on math_private.h to get a definition of bool. Tested for x86_64 and x86, and with build-many-glibcs.py. * math/fromfp.h: Do not include <math_private.h>. * math/s_cacosh_template.c: Likewise. * math/s_casin_template.c: Likewise. * math/s_casinh_template.c: Likewise. * math/s_ccos_template.c: Likewise. * math/s_cproj_template.c: Likewise. * math/s_fdim_template.c: Likewise. * math/s_fmaxmag_template.c: Likewise. * math/s_fminmag_template.c: Likewise. * math/s_iseqsig_template.c: Likewise. * math/s_ldexp_template.c: Likewise. * math/s_nextdown_template.c: Likewise. * math/w_log1p_template.c: Likewise. * math/w_scalbln_template.c: Likewise. * sysdeps/aarch64/fpu/feholdexcpt.c: Likewise. * sysdeps/aarch64/fpu/fesetround.c: Likewise. * sysdeps/aarch64/fpu/fgetexcptflg.c: Likewise. * sysdeps/aarch64/fpu/ftestexcept.c: Likewise. * sysdeps/aarch64/fpu/s_llrint.c: Likewise. * sysdeps/aarch64/fpu/s_llrintf.c: Likewise. * sysdeps/aarch64/fpu/s_lrint.c: Likewise. * sysdeps/aarch64/fpu/s_lrintf.c: Likewise. * sysdeps/i386/fpu/s_atanl.c: Likewise. * sysdeps/i386/fpu/s_f32xaddf64.c: Likewise. * sysdeps/i386/fpu/s_f32xsubf64.c: Likewise. * sysdeps/i386/fpu/s_fdim.c: Likewise. * sysdeps/i386/fpu/s_logbl.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/i386/fpu/s_significandl.c: Likewise. * sysdeps/ia64/fpu/s_matherrf.c: Likewise. * sysdeps/ia64/fpu/s_matherrl.c: Likewise. * sysdeps/ieee754/dbl-64/s_atan.c: Likewise. * sysdeps/ieee754/dbl-64/s_cbrt.c: Likewise. * sysdeps/ieee754/dbl-64/s_fma.c: Likewise. * sysdeps/ieee754/dbl-64/s_fmaf.c: Likewise. * sysdeps/ieee754/flt-32/s_cbrtf.c: Likewise. * sysdeps/ieee754/k_standardf.c: Likewise. * sysdeps/ieee754/k_standardl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_copysignl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_finitel.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_fpclassifyl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isinfl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isnanl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_signbitl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_cbrtl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c: Likewise. * sysdeps/ieee754/s_signgam.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modf.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modff.c: Likewise. * sysdeps/powerpc/power7/fpu/s_logbf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_ceil.c: Likewise. * sysdeps/riscv/rv64/rvd/s_floor.c: Likewise. * sysdeps/riscv/rv64/rvd/s_nearbyint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rv64/rvd/s_roundeven.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rvd/s_finite.c: Likewise. * sysdeps/riscv/rvd/s_fmax.c: Likewise. * sysdeps/riscv/rvd/s_fmin.c: Likewise. * sysdeps/riscv/rvd/s_fpclassify.c: Likewise. * sysdeps/riscv/rvd/s_isinf.c: Likewise. * sysdeps/riscv/rvd/s_isnan.c: Likewise. * sysdeps/riscv/rvd/s_issignaling.c: Likewise. * sysdeps/riscv/rvf/fegetround.c: Likewise. * sysdeps/riscv/rvf/feholdexcpt.c: Likewise. * sysdeps/riscv/rvf/fesetenv.c: Likewise. * sysdeps/riscv/rvf/fesetround.c: Likewise. * sysdeps/riscv/rvf/feupdateenv.c: Likewise. * sysdeps/riscv/rvf/fgetexcptflg.c: Likewise. * sysdeps/riscv/rvf/ftestexcept.c: Likewise. * sysdeps/riscv/rvf/s_ceilf.c: Likewise. * sysdeps/riscv/rvf/s_finitef.c: Likewise. * sysdeps/riscv/rvf/s_floorf.c: Likewise. * sysdeps/riscv/rvf/s_fmaxf.c: Likewise. * sysdeps/riscv/rvf/s_fminf.c: Likewise. * sysdeps/riscv/rvf/s_fpclassifyf.c: Likewise. * sysdeps/riscv/rvf/s_isinff.c: Likewise. * sysdeps/riscv/rvf/s_isnanf.c: Likewise. * sysdeps/riscv/rvf/s_issignalingf.c: Likewise. * sysdeps/riscv/rvf/s_nearbyintf.c: Likewise. * sysdeps/riscv/rvf/s_roundevenf.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Include <stdbool.h> instead of <math_private.h>. * sysdeps/riscv/rvf/s_rintf.c: Likewise.
