Generate the DWARF stack frame decode operations in the function prologue for ARM/Thumb functions. Patch by Keith Walker! llvm-svn: 201423
2014-02-15 01:19:07 +08:00
; ARM EHABI integrated test
; This test case checks whether the ARM DWARF stack frame directives
; are properly generated or not.
; We have to check several cases:
; (1) arm with -disable-fp-elim
; (2) arm without -disable-fp-elim
; (3) armv7 with -disable-fp-elim
; (4) armv7 without -disable-fp-elim
; (5) thumb with -disable-fp-elim
; (6) thumb without -disable-fp-elim
; (7) thumbv7 with -disable-fp-elim
; (8) thumbv7 without -disable-fp-elim
[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635. Saleem pointed out that since symbolic register names are much easier to read, it would be good if we could turn them off only when we really need to because we're using an external assembler.

IR: Give 'DI' prefix to debug info metadata Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. llvm-svn: 236120

DebugInfo: Move new hierarchy into place Move the specialized metadata nodes for the new debug info hierarchy into place, finishing off PR22464. I've done bootstraps (and all that) and I'm confident this commit is NFC as far as DWARF output is concerned. Let me know if I'm wrong :). The code changes are fairly mechanical: - Bumped the "Debug Info Version". - `DIBuilder` now creates the appropriate subclass of `MDNode`. - Subclasses of DIDescriptor now expect to hold their "MD" counterparts (e.g., `DIBasicType` expects `MDBasicType`). - Deleted a ton of dead code in `AsmWriter.cpp` and `DebugInfo.cpp` for printing comments. - Big update to LangRef to describe the nodes in the new hierarchy. Feel free to make it better. Testcase changes are enormous. There's an accompanying clang commit on its way. If you have out-of-tree debug info testcases, I just broke your build. - `upgrade-specialized-nodes.sh` is attached to PR22564. I used it to update all the IR testcases. - Unfortunately I failed to find way to script the updates to CHECK lines, so I updated all of these by hand. This was fairly painful, since the old CHECKs are difficult to reason about. That's one of the benefits of the new hierarchy. This work isn't quite finished, BTW. The `DIDescriptor` subclasses are almost empty wrappers, but not quite: they still have loose casting checks (see the `RETURN_FROM_RAW()` macro). Once they're completely gutted, I'll rename the "MD" classes to "DI" and kill the wrappers. I also expect to make a few schema changes now that it's easier to reason about everything. llvm-svn: 231082

ScheduleDAGInstrs: In functions with tail calls PseudoSourceValues are not non-aliasing distinct objects The code that builds the dependence graph assumes that two PseudoSourceValues don't alias. In a tail calling function two FixedStackObjects might refer to the same location. Worse 'immutable' fixed stack objects like function arguments are not immutable and will be clobbered. Change this so that a load from a FixedStackObject is not invariant in a tail calling function and don't return a PseudoSourceValue for an instruction in tail calling functions when building the dependence graph so that we handle function arguments conservatively. Fix for PR23459. rdar://20740035 llvm-svn: 236916

[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635.

[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635. Saleem pointed out that since symbolic register names are much easier to read, it would be good if we could turn them off only when we really need to because we're using an external assembler.

ARM: When spilling extra registers for alignment, prefer low registers on all Thumb targets. This makes it more likely that we can use the 16-bit push and pop instructions on Thumb-2, saving around 4 bytes per function. Differential Revision: http://reviews.llvm.org/D9165 llvm-svn: 235637
