## Check that BOLT handles code with jrcxz instruction that has a one-byte ## signed offset restriction. If we try to separate jrcxz instruction from its ## destination, e.g. by placing it in a different code fragment, then the link ## step will fail. # REQUIRES: system-linux # RUN: llvm-mc -filetype=obj -triple x86_64-unknown-unknown %s -o %t.o # RUN: link_fdata %s %t.o %t.fdata # RUN: llvm-strip --strip-unneeded %t.o # RUN: %clang %cflags %t.o -o %t.exe -Wl,-q ## Disable relocation mode to leave main fragment in its original location. # RUN: llvm-bolt %t.exe -o %t.bolt --data %t.fdata --reorder-blocks=ext-tsp \ # RUN: --split-functions --relocs=0 .text .globl main .type main,@function main: # FDATA: 0 [unknown] 0 1 main 0 0 1 # FDATA: 1 main 0 1 main #.hot# 0 1 .cfi_startproc jrcxz .Lcold .hot: ret .Lcold: xorl %eax,%eax ret .cfi_endproc .size main,.-main
