# The first chunk is to stop gcc generating stupid assembler output
|
||||
# for jump tables. This change is already in gcc-3.3.
|
||||
# The second chunk is to stop gcc doing an ICE on libc/stdio/vfprintf.c.
|
||||
# This one has been committed to the gcc mainline and is due to go in
|
||||
# gcc-3.3.1, but is *not* in gcc-3.3-release. Its changelog:
|
||||
# * config/i386/i386.c (ix86_split_long_move): Fix base register
|
||||
# mode for XFmode splits for TARGET_64BIT.
