From 5e3c3a0ae5d194f0a464aaaa71d764d96f2e7245 Mon Sep 17 00:00:00 2001 From: Chen Li Date: Tue, 13 Oct 2020 14:31:52 +0800 Subject: alpha: remove undef inline in compiler.h since 889b3c1245de48ed0cacf7aebb25c489d3e4a3e9, CONFIG_OPTIMIZE_INLINING is removed entirely and inline is always defined to `inline __gnu_inline __inline_maybe_unused notrace` in compiler_types.h Besides, undef inline here also means it never use __attribute__((__gnu_inline__)), so `extern inline` function can never be defined header files, otherwise multiple definition errors will happen, e.g. if multiple translation units use alpha/include/asm/pal.h will report multiple definitions, because there are many extern inline function definitions in this header. ``` c extern inline TYPE NAME(void) \ { \ register TYPE __r0 __asm__("$0"); \ __asm__ __volatile__( \ ... ``` Ofc, it is also ok to remove `extern` in `extern inline` here, then all of iso c99 and gnuc99/89 are ok, but there are also other alpha headers have such function definitions.
