--- Comment #3 from kelvin at gcc dot gnu.org --- Author: kelvin Date: Wed Mar 1 14:43:02 2017 New Revision: 245811 URL: https://gcc.gnu.org/viewcvs?rev=245811&root=gcc&view=rev Log: gcc/ChangeLog: 2017-03-01 Kelvin Nilsen <kel...@gcc.gnu.org> PR target/79395 * config/rs6000/altivec.h (vec_ctz and others): Change the preprocessor macro that controls conditional compilation from _ARCH_PWR9 to __POWER9_VECTOR__. (vec_all_ne): Change parameterization of __altivec_scalar_pred macro expansion under preprocessor #ifdef __POWER9_VECTOR__ control (instead of _ARCH_PWR9 control) so that template definition uses power9-specific function. (vec_any_eq): Likewise. (vec_all_ne): Change macro definition to use a power9-specific expansion under #ifdef __POWER9_VECTOR__ control (instead of _ARCH_PWR9 control). (vec_any_eq) Likewise. * config/rs6000/rs6000-builtin.def (CMPNEF): Remove BU_P9V_AV_2 expansion for CMPNEF to remove support for xvcmpnesp instruction. (CMPNED): Remove BU_P9V_AV2 expansion for CMPNED to remove support for xvcmpnedp instruction. (VCMPNEB_P): Replace BU_P9V_AV_P macro expansion with BU_P9V_AV_2 macro expansion so that Power9 implementation of vec_all_ne does not use the AltiVec predicate framework. (VCMPNEH_P): Likewise. (VCMPNEW_P): Likewise. (VCMPNED_P): Likewise. (VCMPNEFP_P): Likewise. (VCMPNEDP_P): Likewise. (VCMPAEB_P): Add BU_P9V_AV_2 macro expansion to change implementation of vec_any_eq to not use AltiVec predicate framework. (VCMPAEH_P): Likewise. (VCMPAEW_P): Likewise. (VCMPAED_P): Likewise. (VCMPAEFP_P): Likewise. (VCMPAEDP_P): Likewise. (VCMPNE_P): Replace BU_P9V_OVERLOAD_P macro expansion with BU_P9V_OVERLOAD_2 so that Power9 implementation of vec_all_ne does not use the AltiVec predicate framework. (VCMPAE_P): Add BU_P9V_OVERLOAD_2 macro to change implementation of vec_any_eq to not use AltiVec predicate framework. * config/rs6000/rs6000-c.c (rs6000_target_modify_macros): Add support for predefined __POWER9_VECTOR__ macro to indicate that Power9 instruction selection is enabled. (altivec_overloaded_builtins): Remove extraneous ALTIVEC_BUILTIN_VEC_CMPNE entry for overloaded function argument types RS6000_BTI_bool_V16QI and RS6000_BTI_bool_V16QI. Remove erroneous ALTIVEC_BUILTIN_VEC_CMPNE entry for overloaded function argument types RS6000_BTI_bool_V4SI andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to P9V_BUILTIN_CMPNEF to force use of instructions not specific to Power9 for implementations of vec_cmpne. Change the signature for all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function (representing vec_all_ne) to remove the previously described first argument of type RS6000_BTI_INTSI, as this was an artifact of reliance on the AltiVec predicate framework, which is no longer used in the implementation of these functions. Add P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries since, unlike the AltiVec predicate framework implementation, we do not share function descriptors between vec_alle and vec_anyeq. (altivec_resolve_overloaded_builtin): Add SFmode and DFmode to the set of modes that receive special treatment even when TARGET_P9_VECTOR is true. The special treatment emits code that does not depend on Power9 instructions. * config/rs6000/vector.md (vector_ne_<mode>_p): Change this define_expand to not rely on AltiVec predicate framework. (vector_ae_<mode>p): New define_expand to represent vec_any_eq function. (vector_ne_v2di_p): Change this define_expand to not rely on AltiVec predicate framework. (vector_ae_v2di_p): New define_expand to represent vec_any_eq function. (vector_ne_<mode>_p): Change this define_expand to not rely on AltiVec predicate framework. (vector_ae_<mode>p): New define_expand to represent vec_any_eq function. * config/rs6000/vsx.md (*vsx_ne_<mode>_p): For modes VSX_EXTRACT_I (V16QI, V8HI, V4SI), correct a typo in the code emitted for this define_insn pattern. (*vsx_ne_<mode>_p): For modes VSX_F (V4SF and V2DF), remove this define_insn pattern because the xvcmpne<VSs>. instruction is not supported. (vcmpne<VSs>): Remove this define_insn because xvcmpne<VSs> instruction is not supported. gcc/testsuite/ChangeLog: 2017-03-01 Kelvin Nilsen <kel...@gcc.gnu.org> PR target/79395 * gcc.target/powerpc/vsu/vec-all-ne-10.c: Change scan-assembler pattern to look for vcmpequd. instead of vcmpnew. * gcc.target/powerpc/vsu/vec-all-ne-14.c: Likewise. * gcc.target/powerpc/vsu/vec-all-ne-7.c: Change scan-assembler pattern to look for xvcmpeqsp. instead of xvcmpnesp. * gcc.target/powerpc/vsu/vec-all-ne-8.c: Change scan-assembler to look for xvcmpeqdp. instead of xvcmpnedp. * gcc.target/powerpc/vsu/vec-all-ne-9.c: Change scan-assembler to look for vcmpequd. instead of vcmpnew. * gcc.target/powerpc/vsu/vec-any-eq-10.c: Likewise. * gcc.target/powerpc/vsu/vec-any-eq-14.c: Likewise. * gcc.target/powerpc/vsu/vec-any-eq-7.c: Change scan-assembler to look for xvcmpeqsp. instead of xvcmpnesp. * gcc.target/powerpc/vsu/vec-any-eq-8.c: Change scan-assembler to look for xvcmpeqdp. instead of xvcmpnedp. * gcc.target/powerpc/vsu/vec-any-eq-9.c: Change scan-assembler to look for vcmpequd. instead of vcmpnew. * gcc.target/powerpc/vsu/vec-cmpne-8.c: Change scan-assembler to look for vcmpeqsp instead of xvcmpnesp. * gcc.target/powerpc/vsu/vec-cmpne-9.c: Change scan-assembler to look for xvcmpeqdp instead of xvcmpnedp.
