10 years ago[MC/DWARF] Support .debug_frame / .debug_line code alignment factors
Ulrich Weigand [Wed, 12 Jun 2013 14:46:54 +0000 (14:46 +0000)]
[MC/DWARF] Support .debug_frame / .debug_line code alignment factors

I've been comparing the object file output of LLVM's integrated
assembler against the external assembler on PowerPC, and one
area where differences still remain are in DWARF sections.

In particular, the GNU assembler generates .debug_frame and
.debug_line sections using a code alignment factor of 4, since
all PowerPC instructions have size 4 and must be aligned to a
multiple of 4.  However, current MC code hard-codes a code
alignment factor of 1.

This patch changes this by adding a "minimum instruction alignment"
data element to MCAsmInfo and using this as code alignment factor.

This requires passing a MCContext into MCDwarfLineAddr::Encode
and MCDwarfLineAddr::EncodeAdvanceLoc.  Note that one caller,
MCDwarfLineAddr::Write, didn't actually have that information
available.  However, it turns out that this routine is in fact
never used in the whole code base, so the patch simply removes
it.  If it turns out to be needed again at a later time, it
could be re-added with an updated interface.

10 years agoRefine the ARM EHABI test cases.
Logan Chien [Sun, 9 Jun 2013 12:36:57 +0000 (12:36 +0000)]
Refine the ARM EHABI test cases.

Since we have ARM unwind directive parser and assembler, we
can check the correctness in two stages:

1. From LLVM assembly (.ll) to ARM assembly (.s)
2. From ARM assembly (.s) to ELF object file (.o)

We already have several "*.s to *.o" test cases.  This CL adds
some "*.ll to *.s" test cases and removes the redundant "*.ll to *.o"
test cases.

New test cases to check "*.ll to *.s" code generator:

- ehabi.ll: Check the correctness of the generated unwind directives.
- section-name.ll: Check the section name of functions.

Removed test cases:

- ehabi-mc-cantunwind.ll
  (Covered by ehabi-cantunwind.ll, and eh-directive-cantunwind.s)
- ehabi-mc-compact-pr0.ll
  (Covered by ehabi.ll, eh-compact-pr0.s, eh-directive-save.s, and

10 years agoFix ARM unwind opcode assembler in several cases.
Logan Chien [Sun, 9 Jun 2013 12:22:30 +0000 (12:22 +0000)]
Fix ARM unwind opcode assembler in several cases.

Changes to ARM unwind opcode assembler:

* Fix multiple .save or .vsave directives.  Besides, the
  order is preserved now.

* For the directives which will generate multiple opcodes,
  such as ".save {r0-r11}", the order of the unwind opcode
  is fixed now, i.e. the registers with less encoding value
  are popped first.

* Fix the $sp offset calculation.  Now, we can use the
  .setfp, .pad, .save, and .vsave directives at any order.

Changes to test cases:

* Add test cases to check the order of multiple opcodes
  for the .save directive.

* Fix the incorrect $sp offset in the test case.  The
  stack pointer offset specified in the test case was
  incorrect.  (Changed test cases: ehabi-mc-section.ll and
  ehabi-mc.ll)

* The opcode to restore $sp are slightly reordered.  The
  behavior are not changed, and the new output is same
  as the output of GNU as.  (Changed test cases:
  eh-directive-pad.s and eh-directive-setfp.s)
