Dehao Chen 967f2c7d51 Add -debug-info-for-profiling to emit more debug info for sample pgo profile collection ... Summary: SamplePGO binaries built with -gmlt to collect profile. The current -gmlt debug info is limited, and we need some additional info: * start line of all subprograms * linkage name of all subprograms * standalone subprograms (functions that has neither inlined nor been inlined) This patch adds these information to the -gmlt binary. The impact on speccpu2006 binary size (size increase comparing with -g0 binary, also includes data for -g binary, which does not change with this patch): -gmlt(orig) -gmlt(patched) -g 433.milc 4.68% 5.40% 19.73% 444.namd 8.45% 8.93% 45.99% 447.dealII 97.43% 115.21% 374.89% 450.soplex 27.75% 31.88% 126.04% 453.povray 21.81% 26.16% 92.03% 470.lbm 0.60% 0.67% 1.96% 482.sphinx3 5.77% 6.47% 26.17% 400.perlbench 17.81% 19.43% 73.08% 401.bzip2 3.73% 3.92% 12.18% 403.gcc 31.75% 34.48% 122.75% 429.mcf 0.78% 0.88% 3.89% 445.gobmk 6.08% 7.92% 42.27% 456.hmmer 10.36% 11.25% 35.23% 458.sjeng 5.08% 5.42% 14.36% 462.libquantum 1.71% 1.96% 6.36% 464.h264ref 15.61% 16.56% 43.92% 471.omnetpp 11.93% 15.84% 60.09% 473.astar 3.11% 3.69% 14.18% 483.xalancbmk 56.29% 81.63% 353.22% geomean 15.60% 18.30% 57.81% Debug info size change for -gmlt binary with this patch: 433.milc 13.46% 444.namd 5.35% 447.dealII 18.21% 450.soplex 14.68% 453.povray 19.65% 470.lbm 6.03% 482.sphinx3 11.21% 400.perlbench 8.91% 401.bzip2 4.41% 403.gcc 8.56% 429.mcf 8.24% 445.gobmk 29.47% 456.hmmer 8.19% 458.sjeng 6.05% 462.libquantum 11.23% 464.h264ref 5.93% 471.omnetpp 31.89% 473.astar 16.20% 483.xalancbmk 44.62% geomean 16.83% Reviewers: davidxl, echristo, dblaikie Reviewed By: echristo, dblaikie Subscribers: aprantl, probinson, llvm-commits, mehdi_amini Differential Revision: https://reviews.llvm.org/D25434 llvm-svn: 292457		2017-01-19 00:44:11 +00:00
