From cf635fad02c1b861708756e34394a050a24e1cc1 Mon Sep 17 00:00:00 2001 From: Daniel Sanders Date: Tue, 24 Jun 2014 12:26:49 +0000 Subject: [PATCH] [mips] Use __clear_cache builtin instead of cacheflush() in Unix Memory::InvalidateInstructionCache() MIPS64 Android bionic has removed cacheflush(). Use __clear_cache() instead for 32-bit and 64-bit MIPS Patch by Duane Sand llvm-svn: 211588 --- llvm/lib/Support/Unix/Memory.inc | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) diff --git a/llvm/lib/Support/Unix/Memory.inc b/llvm/lib/Support/Unix/Memory.inc index c9d89a8..cae39d4 100644 --- a/llvm/lib/Support/Unix/Memory.inc +++ b/llvm/lib/Support/Unix/Memory.inc @@ -333,23 +333,15 @@ void Memory::InvalidateInstructionCache(const void *Addr, for (intptr_t Line = StartLine; Line < EndLine; Line += LineSize) asm volatile("icbi 0, %0" : : "r"(Line)); asm volatile("isync"); -# elif (defined(__arm__) || defined(__aarch64__)) && defined(__GNUC__) +# elif (defined(__arm__) || defined(__aarch64__) || defined(__mips__)) && defined(__GNUC__) // FIXME: Can we safely always call this for __GNUC__ everywhere? + // Use compiler's builtin const char *Start = static_cast(Addr); const char *End = Start + Len; __clear_cache(const_cast(Start), const_cast(End)); # elif defined(__mips__) const char *Start = static_cast(Addr); -# if defined(ANDROID) - // The declaration of "cacheflush" in Android bionic: - // extern int cacheflush(long start, long end, long flags); - const char *End = Start + Len; - long LStart = reinterpret_cast(const_cast(Start)); - long LEnd = reinterpret_cast(const_cast(End)); - cacheflush(LStart, LEnd, BCACHE); -# else cacheflush(const_cast(Start), Len, BCACHE); -# endif # endif #endif // end apple -- 2.7.4
