[Valgrind-developers] valgrind: r3579 - trunk/coregrind

[<sv...@va...>]

Author: sewardj
Date: 2005-04-28 10:40:53 +0100 (Thu, 28 Apr 2005)
New Revision: 3579

Modified:
   trunk/coregrind/m_debuglog.c
Log:
Even more pissing with inline asm around to placate gcc-3.4 -fpic.  We
can't trash %ebx without gcc getting unhappy, so trash %edi instead.
