gcc 2.95.2 and checker: invalid asm constructs

[Claus Fischer <claus dot fischer at intel dot com>]

Despite my workplace ;) I'm not knowledgeable in assembler
coding. I'm trying to compile Checker with gcc 2.95.2 when I
get the following messages about invalid asm's.

I know about the 'invalid asm' issue in general (it 'works'
with egcs-2.91.66) but I'm not an assembler guy.

I would be grateful if someone knowledgeable were willing
to tell me off-list how to fix these asm's.
There are probably only 2 or 3 different patterns altogether,
and I should be quite capable of acting as a somewhat enhanced
search-and-replace engine.

I'll try and mail the result to Tristan, the maintainer, finally.


Best regards,

Claus
