Summary: [4.6 regression] lto-plugin.c doesn't compile on IRIX
6.5
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
CC: dave.k...@gcc.gnu.org, i...@google.com
Host: mips-sgi-irix6.5
Target: mips-sgi-irix6.5
Build: mips-sgi-irix6.5
Since the lto-plugin has been converted to the simple-object interface and is
always enabled on ELF targets, mainline doesn't bootstrap any longer on IRIX
6.5:
/vol/gcc/src/hg/trunk/local/lto-plugin/lto-plugin.c: In function
'claim_file_handler':
/vol/gcc/src/hg/trunk/local/lto-plugin/lto-plugin.c:829: error: expected ')'
before 'PRIx64'
cc1: warnings being treated as errors
/vol/gcc/src/hg/trunk/local/lto-plugin/lto-plugin.c:830: error: too few
arguments for format
make[3]: *** [lto-plugin.lo] Error 1
make[3]: Leaving directory `/var/gcc/regression/trunk/6.5-gcc/build/lto-plugin'
The problem is this piece of code:
int t = asprintf (&objname, "%...@0x%" PRIx64, file->name,
(int64_t) file->offset);
IRIX 6.5 only defines PRIx64 in <inttypes.h> inside __c99. Unless we compile
the lto-plugin in C99 mode (which isn't guaranteed to be available in the
bootstrap compiler), this won't work.
Besides, the plugin is useless on IRIX 6.5 anyway since neither gold nor gld
work (cf. PR target/43533).
