Re: [PATCH] microMIPS support


Hello Maciej,

sure I have seen no MIPS arch bugs...

nitpick, be more readonly:

static const char *const mips_compression_strings[] = {

(a) | -> ||
(b) I have found here it is best to expand logical expressions for the patch
    readers, despite author may see it more logical with the parentheses.

return !MSYMBOL_TARGET_FLAG_1 (msym) && !MSYMBOL_TARGET_FLAG_2 (msym);

It can be const.


Thanks,
