This configuration in contrib/config-list.mk
rl78-elf
currently fails to build due to a warning:
gcc/config/rl78/rl78.c: In function ‘void rl78_expand_prologue()’:
gcc/config/rl78/rl78.c:1381:25: error: comparison between signed and unsigned
integer expressions [-Werror=sign-compare]
for (int i = 0; i < ARRAY_SIZE (mduc_regs); i++)
^
(tested with compiling trunk using gcc 6 via
contrib/config-list.mk).
OK for trunk? (I've only verified that it compiles and fixes the
warning; I haven't tested the results).
gcc/ChangeLog:
* config/rl78/rl78.c (rl78_expand_prologue): Convert local
from int to unsigned.
