Subject: [Bug lto/51859] New: wrapped symbols (wrap linker option) do not link
Date: Sat, 14 Jan 2012 12:29:00 -0000 [thread overview]
Message-ID: <bug-51859-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51859
Bug #: 51859
Summary: wrapped symbols (wrap linker option) do not link
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ncahill_alt@yahoo.com
The following command,
> gcc -flto -Wl,-wrap,malloc -o a a.c
produces the following error,
`__wrap_malloc' referenced in section `.text' of
/tmp/ccCKjgAw.ltrans0.ltrans.o: defined in discarded section `.text' of
/tmp/ccREUpxM.o (symbol from plugin)
collect2: ld returned 1 exit status
Here is the test case:
--- a.c ---
void * __wrap_malloc(int bytes)
{
__real_malloc(bytes);
}
int main()
{
int *p = (int *)malloc(4);
*p = 2;
free(p);
return 0;
}
--- end a.c ---
This has the result that xorg-server 1.11.2 does not build with lto enabled.
Thank you.
Neil.
