[Valgrind-developers] Valgrind: r14929 - /trunk/include/valgrind.h

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

Author: sewardj

New Revision: 14929

Log:
arm32-linux: for the magic-call CALL_FN_* macros, add r12 to the asm
trash list.  Not doing so was causing r12 to get corrupted by the
called function, which lead to some very strange failures in Helgrind
on arm32.  Fixes #344033.
