[Libunwind-devel] [patch] Remove unnecessary calls to labs()

[Paul Pluzhnikov]

Greetings,

Roman reports that Clang warns on unnecessary calls to labs():

  taking the absolute value of unsigned type 'unw_word_t' (aka
'unsigned long') has no effect [-Werror,-Wabsolute-value]

Since rs->reg[...].val is unw_word_t and unsigned on all platforms,
this patch removes the unnecessary calls to labs().

Tested on Linux x86_64, no regressions.

Thanks,
