* hist.h (struct histogram)
(histograms, num_histograms): New. * hist.c (find_histogram, find_histogram_for_pc) (read_histogram_header): New. (s_lowpc, s_highpc, lowpc, highpc, hist_num_bins) (hist_sample): Remove. (hist_read_rec): Use the above, and handle multiple histogram records with disjoint address ranges. (hist_write_hist): Support several histogram records. (scale_and_align_entries): Adjust for multiple histograms. (hist_assign_samples_1): New. (hist_assign_samples): Use the above. (hist_clip_symbol_address): New. * hist.h (hist_check_address) (hist_clip_symbol_address): Declare. * gmon_io.c (gmon_out_read, gmon_out_write): Adjust handling of legacy format for multiple histogram changes. * corefile.c (find_call): Check for core_text_space and clip symbol address range here. * vax.c (vax_find_call): Don't check for core_text_space, or clip the symbol's address range here. Use hist_check_address to check call's target address. * sparc.c: Likewise. * tahoe.c: Likewise. * i386.c: Likewise. * mips.c: Likewise. Also use core_text_sect->vma as the base address for code accesses, just like other machine-specific routines do. * gprof.texi: Adjust for the new logic.
