Vargas Caballero Date: Tue, 8 Oct 2024 12:51:19 +0200 cc1: Fix sizeof expressions The commit c863f707 tried to fix expressions like: sizeof((int) 1) and changed the reduction in sizeexp() from unary to cast, but it had the side effect of allowing things like sizeof (int) 1 that is invalid, and having problems with things like sizeof "hello" - 1 The commit 4a0c2ccd tried to fix this last case reverting c863f707 that moved the code to the original point. The problem is that to avoid the ambiguity when a '(' follows a sizeof (because it can be a typename or an expression) then the rule chain unary -> SIZEOF unary -> SIZEOF postfix -> SIZEOF primary -> SIZEOF ( expr ) was collapsed to unary -> SIZEOF ( unary ) because when a ( happend after a SIZEOF token then the next token was looked to see if it was a typename or not to decide to apply the chain: unary -> SIZEOF ( typename ) And it can be seen the problem is that the collapsing was wrong because we should have SIZEOF ( expr ) instead of SIZEOF ( unary ), but still SIZEOF unary when no ( follows the SIZEOF token.

Vargas Caballero Date: Mon, 12 Feb 2024 08:46:53 +0100 as: Reuse symbol and section from libmach This is the next step in the migration to use the types defined in libmach instead of using custom ones that are almost identical to the one used in libmach. A mem pointer was added to the type in libmach but it is expected to be removed soon.

as: Align symbol and section with mach.h

Vargas Caballero Date: Sun, 11 Feb 2024 16:19:30 +0100 as: Align symbol and section with mach.h As uses types very similar to the types used in mach.h and if we want to use libmach in as then we have to align these structures to avoid the collition between them.
