Subject: [PATCH 4/9] i386: Don't use reference of struct ix86_frame
Use reference of struct ix86_frame in ix86_expand_prologue and
ix86_expand_epilogue caused:
raised STORAGE_ERROR : stack overflow or erroneous memory access
make[5]: *** [/export/gnu/import/git/sources/gcc/gcc/ada/Make-generated.in:45: ada/sinfo.h] Error 1
on trunk when bootstrapping GCC with ada on x86-64.
* config/i386/i386.c (ix86_expand_prologue): Don't use reference
of struct ix86_frame.
(ix86_expand_epilogue): Likewise.
