Correctly handle weak undefined symbols. Before we would get a invalid binding (2 == STB_WEAK \| STB_GLOBAL). llvm-svn: 114690 2010-09-23 21:55:14 +02:00			`// RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o - \| elf-dump \| FileCheck %s`

			`// Test that this produces a weak undefined symbol.`

			`.weak foo`
			`.long foo`

Defined weak symbols should have non-zero value. llvm-svn: 117585 2010-10-28 21:39:57 +02:00			`// And that bar is after all local symbols and has non zero value.`
Make sure weak symbols are listed after the local ones. llvm-svn: 115795 2010-10-06 18:47:31 +02:00			`.weak bar`
			`bar:`

Another counter goes decimal. llvm-svn: 136871 2011-08-04 16:27:46 +02:00			`//CHECK: # Symbol 4`
Fixing r116753 r116756 r116777 The failures in r116753 r116756 were caused by a python issue - Python likes to append 'L' suffix to stringified numbers if the number is larger than a machine int. Unfortunately, this causes a divergence of behavior between 32 and 64 bit python versions. I re-crafted elf-dump/common_dump to take care of these issues by: 1. always printing 0x (makes for easy sed/regex) 2. always print fixed length (exactly 2 + numBits/4 digits long) by mod ((2^numBits) - 1) 3. left-padded with '0' There is a residual common routine that is also used by macho-dump (dataToHex) , so I left the 'section_data' test values alone. llvm-svn: 116823 2010-10-19 19:39:10 +02:00			`//CHECK-NEXT: (('st_name', 0x00000005) # 'bar'`
