Hi, I'm posting this patch series for stage1: - 0001-Disable-lang_hooks.gimplify_expr-in-free_lang_data.patch - 0002-Add-gimple_find_sub_bbs.patch - 0003-Factor-optimize_va_list_gpr_fpr_size-out-of-pass_std.patch - 0004-Handle-internal_fn-in-operand_equal_p.patch - 0005-Postpone-expanding-va_arg-until-pass_stdarg.patch
The patch series - based on Michael's initial patch - postpones expanding va_arg until pass_stdarg, which makes pass_stdarg more robust.
Bootstrapped and reg-tested on x86_64 using all languages, with unix/ and unix/-m32 testing.
I'll post the patches in reply to this email. Thanks, - Tom
