gnusrc/gnu/dist/toolchain/gcc/config/vax: vax.h vax.md
Log Message:
Fix long time codegen bug. Only the COMPARE, ADD, MINUS operations actually
set the C(arry) bit appropriately. All other leave it in an indeterminate
(to GCC) state. Mark that by setting CC_NO_OVERFLOW. Change vax.md emission
of branches that use the C bit to use OUTPUT_JUMP so that if CC_NO_OVERFLOW is
set, branches that would normally use the C bit use opcodes that don't use the
C bit (jgtru -> jneq && jlssu -> jeql). Delete the cmpdi pattern.
