[llvm-commits] [PATCH] Thumb2 cond/uncond branch fixup for ELF

[Logan Chien]

Dear all,

  It seems that ARMELFObjectWriter is not translating fixup_t2_condbranch
and fixup_t2_uncondbranch into R_ARM_THM_JUMP24.  As a result, "llc"
can not compile following code correctly with integrated assembler.  I hope
these patches can fix this issue.  Please review.  Thanks!

Sincerely,
Logan


*p.s. Test case to crash llc:*
; RUN: llc -mtriple thumbv7-none-linux-gnueabi -mcpu=cortex-a8 -march=thumb
\
; RUN:   -mattr=thumb2 -filetype=obj -o - < %s | llvm-objdump -r - |
FileCheck %s
define i32 @test_fixup_t2_uncondbranch() {
b0:
  invoke void @__cxa_throw(i8* null, i8* null, i8* null) noreturn
    to label %unreachable unwind label %lpad
; CHECK: {{[0-9]+}} R_ARM_THM_JUMP24 __cxa_throw
