This is a regression fix where non-trivial Objective-C parses would ICE when given -save-temps (ICE in the lexer).
This is a short-term fix for stage-4. ISTM that we should not really be making use of these functions in lexing and hopefully in GCC-15 we can take a look at moving the functionality to a later phase. Tested on i686, powerpc, x86_64 Darwin, x86_64 Linux, pushed to trunk, thanks Iain --- 8< --- The tokenizer makes use of functions that determine if identifiers are interface or class names, and those functions need a hash map to be set up. This ensures that these are initialized before pre-process-only jobs are run. gcc/objc/ChangeLog: * objc-act.cc (objc_init): Initialize interface and class name hash maps before the preprocessor uses them.
