re PR other/61895 (libbacktrace crashes with bus error with empty file argv[0])
PR other/61895
runtime: Ignore small argv[0] file for backtrace.
Reportedly in some cases Docker starts processes with argv[0]
pointing to an empty file. That would cause libgo to pass
that empty file to libbacktrace, which would then fail to do
any backtraces. Everything should work fine if libbacktrace
falls back to /proc/self/exe.
This patch to libgo works around the problem by ignoring
argv[0] if it is a small file, or if stat fails. This is not
a perfect fix but it's an unusual problem.
currently, aarch64 LEGITIMIZE_ADDRESS_P hook will reject all "reg + offset"
address given "offset" is beyond supported range.
while this may be too strict. we should honor the "strict_p" parameter in the
hook. before reload, we accept all offset if it's a frame access, because the
offset may change during later register elimination.
the early reject of "reg + offset" may cause extra registers created, and if
that register live range is across function invoking then callee saved reg
needed, thus introduce extra reg save/restore also.
give a simple example as:
int
test15 (void)
{
unsigned char a[480];
initialize_array (a, 480);

* sem_res.adb (Resolve_Entry_Call): When an entry has
preconditions, the entry call is wrapped in a procedure call
that incorporates the precondition checks. To prevent a double
expansion, with possible duplication of extra formals, that
procedure call must only be pre-analyzed and resolved. Expansion
takes place upon return to the caller Resolve_Call.
