Bug ID: 430158
Summary: below main misses some "optimizations"
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: massif
Assignee: n...@valgrind.org
Reporter: m...@klomp.org
Target Milestone: ---
gcc can do a couple more optimizations for generic_start_main, like
generic_start_main.isra.0 or generic_start_main.constprop.0.isra.0.
For ppc we already recognize generic_start_main.isra.0, but nothing else.
It would probably be good to recognize any optimization in get_fnname_kind like
so:
# if defined(VGO_linux)
VG_STREQ("__libc_start_main", name) || // glibc glibness
VG_STREQ("generic_start_main", name) || // Yellow Dog doggedness
VG_STREQN(19, "generic_start_main.", name) || // gcc optimization
# elif defined(VGO_darwin)
This fixes ./massif/tests/deep-D.vgtest on same setups, and we could then get
rid of ./massif/tests/deep-D.post.diff-ppc64
