* preproc.c: Restore concat rules on context local variablesCyrill Gorcunov2010-10-271-89/+95
| | | | | | | | | This is a backport of commits 8dcbbd7af0d6d07b455de0b6460dca6db6113553 575d4289c9b1fb47774cb79764a24899a69a8d52 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>
* preproc: Issue warning on unterminated %{ constructCyrill Gorcunov2010-10-271-1/+5
| | | | | | | | | | | | | | | As being pointed by "matching braces" topic on [ http://forum.nasm.us/index.php?topic=905.0 ] we don't issue warning on missed match for "{" brace opened. Strictly speaking we should issue error instead and force user to fix asm source code but since it's here for a long time already -- lets be "admissive".

* BR3066383: Restore backward compatibility with token pastingCyrill Gorcunov2010-09-181-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems to be a bit long story for the reason if this bug. But lets be verbose and describe all byte-to-byte. And it is all about preprocessor code, in particular paste_tokens and expand_mmac_params. Initially the problem (not the same but similar) was noticed and fixed in commit ec88c1be. The problem reveals itself with code snippets like | %macro m 1 | %push | %define %$arg %1 | %%top_%$arg: | resb ($ - %%top_%$arg) | %pop | %endmacro So with commits ec88c1be, 51fd86e0, 1f6741fc, 985d880c we did expand local single macro before processing tokens pasting unconditionally. But then it being found that such approach breaks %assign directive. The snippets like below didn't work | %macro m 1 | %push | %assign %$arg %1 | %assign %$arg %1+%$arg | %pop | %endmacro So all these commits were reverted and we just stop pasting tokens in paste_tokens() after TOK_PREPROC_ID (commit 20a94ad7). Unfortunately this breaks %assign with compound preproc id | %macro m3 1 | %push | %assign %$_uses 0 | %rep 4 | %assign %$_ur%$_uses %$_uses | mov ecx, %$_ur%$_uses | %assign %$_uses %$_uses+1 | %endrep | %pop | %endmacro To fix this bug we have to combine two approaches at once, we should continue pasting after TOK_PREPROC_ID and expand sequential TOK_PREPROC_IDs except first one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For now we inform users about their sources need to be updated and also since _all_ context case are legit for single macros only we split lookup into two phases: 1) Lookup in active context, which is perfectly valid 2) Lookup in external contexts, which will be deprecated soon. If (2) happens we yield warning. A typical testcase is --- %macro one 0 %push %$a: %assign %$b 12 %push mov eax, %$a mov eax, %$b ; hit -- context through %pop %pop %endmacro one --- Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>
