It makes LLVM run out of registers even on 64-bit platforms. For example, the following test case fails on darwin. clang -cc1 -O0 -triple x86_64-apple-macosx10.10.0 -emit-obj -fsanitize=address -mstackrealign -o ~/tmp/ex.o -x c ex.c error: inline assembly requires more registers than available void TestInlineAssembly(const unsigned char *S, unsigned int pS, unsigned char *D, unsigned int pD, unsigned int h) { unsigned int sr = 4, pDiffD = pD - 5; unsigned int pDiffS = (pS << 1) - 5; char flagSA = ((pS & 15) == 0), flagDA = ((pD & 15) == 0); asm volatile ( "mov %0, %%"PTR_REG("si")"\n" "mov %2, %%"PTR_REG("cx")"\n" "mov %1, %%"PTR_REG("di")"\n" "mov %8, %%"PTR_REG("ax")"\n" : : "m" (S), "m" (D), "m" (pS), "m" (pDiffS), "m" (pDiffD), "m" (sr), "m" (flagSA), "m" (flagDA), "m" (h) : "%"PTR_REG("si"), "%"PTR_REG("di"), "%"PTR_REG("ax"), "%"PTR_REG("cx"), "%"PTR_REG("dx"), "memory" ); } http://reviews.llvm.org/D10719 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240722 91177308-0d34-0410-b5e6-96231b3b80d8 |
