From: Mike Frysinger Date: Sun, 28 Nov 2021 05:21:09 +0000 (-0500) Subject: sim: cr16: switch to new target-newlib-syscall X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ab230d13fc81986c4a74688e35510a8985dff422;p=binutils-gdb.git sim: cr16: switch to new target-newlib-syscall Use the new target-newlib-syscall module. This is needed to merge all the architectures into a single build, and cr16 has a custom syscall table for its newlib/libgloss port. This allows cleaning up the syscall ifdef logic. We know these will always exist now. --- diff --git a/sim/cr16/Makefile.in b/sim/cr16/Makefile.in index 4d7345a6b51..26f65a0384f 100644 --- a/sim/cr16/Makefile.in +++ b/sim/cr16/Makefile.in @@ -26,7 +26,4 @@ SIM_OBJS = \ SIM_EXTRA_DEPS = simops.h -# This selects the cr16 newlib/libgloss syscall definitions. -NL_TARGET = -DNL_TARGET_cr16 - ## COMMON_POST_CONFIG_FRAG diff --git a/sim/cr16/interp.c b/sim/cr16/interp.c index 18e1db9f739..d63dca50c49 100644 --- a/sim/cr16/interp.c +++ b/sim/cr16/interp.c @@ -36,6 +36,8 @@ #include "gdb/signals.h" #include "opcode/cr16.h" +#include "target-newlib-syscall.h" + struct _state State;
