[uclibc-ng-devel] [PATCH v2] Clang support for gnu_inline attribute

From: Marcus Hähnel <marcus.haehnel(a)kernkonzept.com> Clang also supports the gnu_inline attribute and the __GNUC_STDC_INLINE__ macro (C99 semantics). However, it reports as GCC 4.2 compatible (__GNUC_MINOR__ / __GNUC__) and thus the current defines do not think it can support this. Add clang as an alternative for this support. Documentation shows that this attribute is supported since at least Clang 8. --- include/sys/cdefs.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/sys/cdefs.h b/include/sys/cdefs.h index 9b3a02177..656548c52 100644 --- a/include/sys/cdefs.h +++ b/include/sys/cdefs.h @@ -320,7 +320,7 @@ inline semantics, unless -fgnu89-inline is used.
