'-g' option generates invalid assembly when '*/*' operator is used
Bug is observed when building cpphs-1.19
module A where
x */* y = 42
$ ghc -fforce-recomp A -g
[1 of 1] Compiling A ( A.hs, A.o )
/tmp/ghc23923_0/ghc_2.s: Assembler messages:
/tmp/ghc23923_0/ghc_2.s:17:0: Error: bad expression
/tmp/ghc23923_0/ghc_2.s:17:0:
Warning: missing operand; zero assumed
...
The problem here is the following assembly snippet:
.text
.align 8
.loc 1 3 1 /* */* */
.quad 12884901911
.quad 0
.quad 15
Would it be worthwile using ';' as a comment instead? Don't know if it's universally portable.
