Subject: cmd/6c, cmd/8c: use signed char explicitly in mul.c
X-Git-Tag: go1.1rc2~1907
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=cc224c004d0f389efcbb54251840bbb264ea4826;p=gostls13.git

cmd/6c, cmd/8c: use signed char explicitly in mul.c

On ARM, char is unsigned, and the code generation for
multiplication gets totally broken.

Fixes #4354.
