Passed now fails [PASS => FAIL]: gcc.target/arm/memset-inline-5.c scan-assembler-not vstr You can have a look at: http://cbuild.validation.linaro.org/build/cross-validation/gcc/trunk/215050/report-build-info.html (search for the a57 lines) (The other lines marked as regressions can be ignored: they are caused by your changes in the tests output, I not yet able to associate the new pass with the new fail) Thanks, Christophe. >> >> Thanks, >> Kyrill >> >> 2014-08-19 Kyrylo Tkachov <kyrylo.tkac...@arm.com> >> >> * config/arm/arm.c (output_move_vfp): Use UAL syntax for load/store >> multiple. >> (arm_print_operand): Don't convert real values to decimal >> representation in default case. >> (fp_immediate_constant): Delete. >> * config/arm/arm-protos.h (fp_immediate_constant): Likewise. >> * config/arm/vfp.md (*arm_movsi_vfp): Convert to VFP moves to UAL >> syntax. >> (*thumb2_movsi_vfp): Likewise. >> (*movdi_vfp): Likewise. >> (*movdi_vfp_cortexa8): Likewise. >> (*movhf_vfp_neon): Likewise. >> (*movhf_vfp): Likewise. >> (*movsf_vfp): Likewise. >> (*thumb2_movsf_vfp): Likewise. >> (*movdf_vfp): Likewise. >> (*thumb2_movdf_vfp): Likewise. >> (*movsfcc_vfp): Likewise. >> (*thumb2_movsfcc_vfp): Likewise. >> (*movdfcc_vfp): Likewise. >> (*thumb2_movdfcc_vfp): Likewise. >> >> 2014-08-19 Kyrylo Tkachov <kyrylo.tkac...@arm.com> >> >> * gcc.target/arm/pr51835.c: Update expected assembly. >> * gcc.target/arm/vfp-1.c: Likewise. >> * gcc.target/arm/vfp-ldmdbd.c: Likewise. >> * gcc.target/arm/vfp-ldmdbs.c: Likewise. >> * gcc.target/arm/vfp-ldmiad.c: Likewise. >> * gcc.target/arm/vfp-ldmias.c: Likewise. >> * gcc.target/arm/vfp-stmdbd.c: Likewise. >> * gcc.target/arm/vfp-stmdbs.c: Likewise. >> * gcc.target/arm/vfp-stmiad.c: Likewise. >> * gcc.target/arm/vfp-stmias.c: Likewise.
