[uclibc-ng-devel] [PATCH] xtensa: use compiler-provided XCHAL macros

Starting with gcc-13 the compiler provides configuration-specific macro definitions for the target xtensa core. Use them when available instead of the configuration overlay file xtensa-config.h Signed-off-by: Max Filippov <jcmvbkbc(a)gmail.com> --- .../sysdeps/linux/xtensa/bits/xtensa-config.h | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/libc/sysdeps/linux/xtensa/bits/xtensa-config.h b/libc/sysdeps/linux/xtensa/bits/xtensa-config.h index b99928b1e058..bfcd571d26e2 100644 --- a/libc/sysdeps/linux/xtensa/bits/xtensa-config.h +++ b/libc/sysdeps/linux/xtensa/bits/xtensa-config.h @@ -32,21 +32,41 @@ macros. */ #undef XCHAL_HAVE_NSA +#ifdef __XCHAL_HAVE_NSA +#define XCHAL_HAVE_NSA __XCHAL_HAVE_NSA +#else #define XCHAL_HAVE_NSA 1 +#endif #undef XCHAL_HAVE_LOOPS +#ifdef __XCHAL_HAVE_LOOPS +#define XCHAL_HAVE_LOOPS __XCHAL_HAVE_LOOPS +#else #define XCHAL_HAVE_LOOPS 1 +#endif /* Assume the maximum number of AR registers.
