[Qemu-devel] [PATCH rebased/amended] microblaze: fix custom fprintf with _FORTIFY_SOURCE=2 |
Date: |
Mon, 19 Apr 2010 22:36:02 +0200 |
From: Thomas Monjalon <address@hidden>
Using GCC-4.2.4-1ubuntu4, there is a warning:
microblaze-dis.c:792: warning: unused variable 'fprintf'
Indeed, fprintf() is shadowed by a custom redefinition but is not used because
of FORTIFY_SOURCE option which replace calls to fprintf() by fprintf_chk().
It is fixed by renaming the variable which prevents from hazardous shadowing.
