From 39646d96e76aea5d20bffb386233a0dbb5932a21 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Fri, 7 Sep 2012 17:25:13 +0000 Subject: MC: Overhaul handling of .lcomm - Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163395 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/MC/ELF/lcomm.s | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 test/MC/ELF/lcomm.s (limited to 'test/MC/ELF') diff --git a/test/MC/ELF/lcomm.s b/test/MC/ELF/lcomm.s new file mode 100644 index 0000000000..ae8d0baa33 --- /dev/null +++ b/test/MC/ELF/lcomm.s @@ -0,0 +1,21 @@ +// RUN: llvm-mc -triple i386-pc-linux-gnu %s -filetype=obj -o - | elf-dump | FileCheck %s + +.lcomm A, 5 +.lcomm B, 32 << 20 + +// CHECK: (('st_name', 0x00000001) # 'A' +// CHECK: ('st_value', 0x00000000) +// CHECK: ('st_size', 0x00000005) +// CHECK: ('st_bind', 0x0) +// CHECK: ('st_type', 0x1) +// CHECK: ('st_other', 0x00) +// CHECK: ('st_shndx', 0x0003) +// CHECK: ), +// CHECK: (('st_name', 0x00000003) # 'B' +// CHECK: ('st_value', 0x00000005) +// CHECK: ('st_size', 0x02000000) +// CHECK: ('st_bind', 0x0) +// CHECK: ('st_type', 0x1) +// CHECK: ('st_other', 0x00) +// CHECK: ('st_shndx', 0x0003) +// CHECK: ), -- cgit v1.2.3
