Author: jakub Date: Tue Sep 15 20:12:18 2009 New Revision: 151729 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=151729 Log: PR target/41175 PR target/40677 * config/rs6000/rs6000.c (no_global_regs_above): Fix precedence problem. (SAVRES_NOINLINE_GPRS_SAVES_LR, SAVRES_NOINLINE_FPRS_SAVES_LR, SAVRES_NOINLINE_FPRS_DOESNT_RESTORE_LR): New strategy bits. (rs6000_savres_strategy): Always save FP registers inline if the target doesn't support hardware double-precision. Set the above bits in return value when needed. (rs6000_savres_routine_sym): Fix computation for cache selector. Mark the generated symbol as a function. Rename exitp argument to lr. Move code for determining the name of the symbol... (rs6000_savres_routine_name): ...here. New function. Add cases for getting the names right on AIX and 64-bit Linux. (savres_routine_name): New variable. (rs6000_make_savres_rtx): Rename exitp argument to lr. Don't assert lr isn't set when savep. Use r12 resp. r1 instead of r11 depending on what the target routine uses as a base register. If savep && lr describe saving of r0 into memory slot. (rs6000_emit_prologue): Correct use of call_used_regs. Fix out of line calls for AIX ABI. (rs6000_output_function_prologue): Use rs6000_savres_routine_name to determine FP save/restore functions. (rs6000_emit_stack_reset): Handle savres if sp_offset != 0 and frame_reg_rtx != sp_reg_rtx. Use gen_add3_insn instead of gen_addsi3. (rs6000_emit_epilogue): Adjust computation of restore_lr. Duplicate restoration of LR and execute the appropriate one depending on whether GPRs are being restored inline. Set r11 from offsetted frame_reg_rtx instead of sp_reg_rtx; if frame_reg_rtx is r11, adjust sp_offset. Use gen_add3_insn instead of gen_addsi3. Fix out of line calls for AIX ABI. * config/rs6000/rs6000.md (*return_and_restore_fpregs_aix_<mode>): New insn. * config/rs6000/spe.md (*save_gpregs_spe): Use explicit match for register 11. (*restore_gpregs_spe): Likewise. (*return_and_restore_gpregs_spe): Likewise. * config/rs6000/linux64.h (SAVE_FP_SUFFIX, RESTORE_FP_SUFFIX): Define to empty string unconditionally. * config/rs6000/sysv4.h (SAVE_FP_SUFFIX, RESTORE_FP_SUFFIX): Define to empty string unconditionally. (GP_SAVE_INLINE, FP_SAVE_INLINE): Handle TARGET_64BIT the same as !TARGET_64BIT. * gcc.target/powerpc/pr41175.c: New test. Added: trunk/gcc/testsuite/gcc.target/powerpc/pr41175.c Modified: trunk/gcc/ChangeLog trunk/gcc/config/rs6000/linux64.h trunk/gcc/config/rs6000/rs6000.c trunk/gcc/config/rs6000/rs6000.md trunk/gcc/config/rs6000/spe.md trunk/gcc/config/rs6000/sysv4.h trunk/gcc/testsuite/ChangeLog -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41175
