H. Peter Anvin	d784a083a3	preproc: unify token-pasting code ... Unify the token-pasting code between the macro expansion and the preprocessor parameter case. Parameterize whether or not to handle %+ tokens during expansion (%+ tokens have late binding semantics.) Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>	2009-04-20 14:01:18 -07:00
H. Peter Anvin	6125b62403	preproc: fix more token pasting cases ... "+" can be a separate token that ends up having to get pulled into the middle of a floating-point constant. It's not even that strange. Signed-off-by: H. Peter Anvin <hpa@zytor.com>	2009-04-08 14:02:25 -07:00
H. Peter Anvin	9bb46df4b7	Handle weird cases of token pasting ... Especially when token pasting involves floating-point numbers, we can have some really strange effects from token pasting: for example, pasting the two tokens "xyzzy" and "1e+10" ends up with *three* tokens: "xyzzy1e" "+" "10". The easiest way to deal with this is to explicitly combine the string and then run tokenize() on it. Signed-off-by: H. Peter Anvin <hpa@zytor.com>	2009-04-07 21:59:24 -07:00
