Subject:         * config/tc-xtensa.h (resource_table): Change units to unsigned chars.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0bf60745767d2465c81ee57ae7705a62d6d8fafe;p=binutils-gdb.git

    * config/tc-xtensa.h (resource_table): Change units to unsigned chars.
        * config/tc-xtensa.c (new_resource_table): Likewise.
        (resize_resource_table): Likewise.
        (release_resources): Fix assertion for unsigned values.
