Hi,
Unfortunately the offending fix of mine causes 'y...' to be treated as a
single identifier instead of y followed by TOK_DOTS which is gcc extension
to designate 'y' to become __VA_ARGS__ replacement. Nasty!
If going forward with the commit the plan is in tccpp.c around line 1337
(nice line:-)) to check if an identifier is ending with '...' and set
is_vaargs instead of current check for TOK_DOTS on next token. That or
switching PARSE_FLAG_ASM_FILE off for preprocessor directives in .S files.
Will have to write a failing test too.
cheers,
</wqw>

Hi!
Patch "Identifiers can start and/or contain '.' in PARSE_FLAG_ASM_FILE"
breaks preprocessing on *.S
A test program (from a linux-2.4.26)
#define SRC(y...) \
9999: y; \
.section __ex_table, "a"; \
.long 9999b, 6001f ; \
.previous
SRC(1: movw (%esi), %bx )
// 029-test.S:7: error: macro 'SRC' used with too many args //
commit_bad=aa1ed616eb01efe353e7c5e829fffbed01b428bd
// Identifiers can start and/or contain '.' in PARSE_FLAG_ASM_FILE
//
// commit_good=17395ea5070bb05681f93ce7a8019c8c863a607b
This test compules OK if changes commut_good..commit_bad are reverted.
