Bug ID: 32224
Summary: Call graph not displayed for coff-go32 (no
function-flag on symbols)
Product: binutils
Version: 2.43.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gprof
Assignee: unassigned at sourceware dot org
Reporter: jwjagersma at gmail dot com
Target Milestone: ---
I'm looking to fix djgpp's profiler support, which is suffering from some
bit-rot. I fixed some issues with mcount in libc, but still don't get a call
graph (all samples are <spontaneous>).
Stepping through gprof, I find that none of the symbols have the 'is_func' flag
set, and it makes cg_tally() drop all the arc entries.
>From what I can tell then, 'core_has_func_syms' (in
core_create_function_syms(),
gprof/corefile.c) should be 0 for coff-go32. Or, the assembler should emit
a function flag on .text symbols.
