DebugInfo: add a test case for data member locations (coverage for r193835) llvm-svn: 193878
2013-11-02 02:25:55 +08:00
; RUN: llc -mtriple=x86_64-linux -O0 -o - -filetype=obj < %s | llvm-dwarfdump -debug-dump=info -| FileCheck %s
Revert "Reverting r193835 due to weirdness with Go..." The cgo problem was that it wants dwarf2 which doesn't support direct constant encoding of the location. So let's add support for dwarf2 encoding (using a location expression) of data member locations. This reverts commit r198385. llvm-svn: 198389

; CHECK: DW_AT_name {{.*}} "c"
DebugInfo: Improve readability of test case added in r193878 The point is to ensure that the attribute in question (DW_AT_data_member_location) is associated with the prior tag, so ensure that we don't see another tag starting between the intended tag and the desired attribute. llvm-svn: 193884

Debug Info: update testing cases to specify the debug info version number. We are going to drop debug info without a version number or with a different version number, to make sure we don't crash when we see bitcode files with different debug info metadata format. llvm-svn: 195504

Revert "Revert "DI: Fold constant arguments into a single MDString"" This reverts commit r218918, effectively reapplying r218914 after fixing an Ocaml bindings test and an Asan crash. The root cause of the latter was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a PR to investigate who requires the loose check (and why). Original commit message follows. -- This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a `\0` character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. llvm-svn: 219010

DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0} A bunch of test cases needed to be cleaned up for this, many my fault - when implementid imported modules I updated test cases by simply duplicating the prior metadata field - which wasn't always the empty metadata entry. llvm-svn: 200731
