scannerlexer.l: Parse and ignore more __asm and __volatile (1.60 KB, patch)
2013-04-20 11:45 UTC, Patrick Welche 		accepted-commit_now Details | Review

Description Thorsten Glaser 2012-06-25 14:49:15 UTC 
While compiling software that’s part of the GNOME stack:

/usr/include/m68k-linux-gnu/bits/byteswap.h:50: syntax error, unexpected identifier, expecting ',' or ';' in '  __asm__ __volatile__ ("ror%.w %#8, %0;"' at '_'

This is g-ir-scanner from gobject-introspection 1.32.1-1 on Debian/m68k.
It doesn’t appear to have any negative outcome, but I thought I’d better report it.

You may be able to prefix it with __extension__ .  I believe some of the other headers use that.

scannerlexer.l: Parse and ignore more __asm and __volatile

In the spirit of c9708af2 also parse and ignore
    
    __asm    [whitespace] volatile
    __asm__  [whitespace] volatile
    __volatile
    __volatile__
    
Ignoring __volatile is cosmetic, but the __asm cases avoid an unwanted VOLATILE token.
