>Environment:
alphaev56-dec-osf4.0d
>Description:
gcc/config/alpha/osf.h 
includes the line
#define ASM_SPEC "%{!mgas:-g %(asm_oldas)} -nocpp %{pg} -O0"

problems with this line include -O0 is sent when mgas is
selected - and gas doesnt support -O0

also -nocpp is Always sent - which is bad when the input file is .s - and needs cpp ... - prehaps gcc should be running cpp on .s - but I couldnt find anywhere that it was programmed to do so.
>How-To-Repeat:
compiling mozilla 0.9.8 - the xpcom/reflect/md/unix 
running make causes gcc calls the OSF as - which core dumps because it cant handle the .s file which contains comments.
After installing gas to try and fix this - gcc just dies at assembly stage no matter what - since -O0 gets passed to as which gas doesnt understand.
>Fix:
modify the ASM_SPEC line to be more intelligent.

 I have indeed subsequently realised this, which prompted
 target/6077: .s with -x assembler-with-cpp breaks mips-tfile
