H.J. Lu d165ca6498 Support profiling PIE [BZ #22284] ... Since PIE can be loaded at any address, we need to subtract load address from PCs. [BZ #22284] * gmon/Makefile [$(have-fpie)$(build-shared) == yesyes] (tests, tests-pie): Add tst-gmon-pie. (CFLAGS-tst-gmon-pie.c): New. (CRT-tst-gmon-pie): Likewise. (tst-gmon-pie-ENV): Likewise. [$(have-fpie)$(build-shared) == yesyes] (tests-special): Likewise. ($(objpfx)tst-gmon-pie.out): Likewise. (clean-tst-gmon-pie-data): Likewise. ($(objpfx)tst-gmon-pie-gprof.out): Likewise. * gmon/gmon.c [PIC]: Include <link.h>. [PIC] (callback): New function. (write_hist): Add an argument for load address. Subtract load address from PCs. (write_call_graph): Likewise. (write_gmon): Call __dl_iterate_phdr to get load address, pass it to write_hist and write_call_graph.
