[ARM] Fix access to stack arguments when re-aligning SP in Armv6m

SP, which is incorrect, as the SP is offset by an unknown amount relative to the

[ARM] Fix codegen for VLD3/VLD4/VST3/VST4 with WB

Code generation of VLD3, VLD4, VST3 and VST4 with register writeback is
broken due to 2 separate bugs:

1) VLD1d64TPseudoWB_register and VLD1d64QPseudoWB_register are missing
   rules to expand them to non pseudo MIR. These are selected for
   ARMISD::VLD3_UPD/VLD4_UPD with v1i64 vectors in SelectVLD.

2) Selection of the right VLD/VST instruction is broken for load and
   store of 3 and 4 v1i64 vectors. SelectVLD and SelectVST are called
   with MIR opcode for fixed writeback (ie increment is access size)
   and call getVLDSTRegisterUpdateOpcode() to select an opcode with
   register writeback if base register update is of a different size.
   Since getVLDSTRegisterUpdateOpcode() only knows about
   VLD1/VLD2/VST1/VST2 the call is currently conditional on the number
   of element in the vector.

   However, VLD1/VST1 is selected by SelectVLD/SelectVST's caller for
   load and stores of 3 or 4 v1i64 vectors. Therefore the opcode is not
   updated which later lead to a fixed writeback instruction being
   constructed with an extra operand for the register writeback.

This patch addresses the two issues as follows:
- it adds the necessary mapping from VLD1d64TPseudoWB_register and
  VLD1d64QPseudoWB_register to VLD1d64Twb_register and
  VLD1d64Qwb_register respectively. Like for the existing _fixed
  variants, the cost of these is bumped for unaligned access.
- it changes the logic in SelectVLD and SelectVSD to call isVLDfixed
  and isVSTfixed respectively to decide whether the opcode should be
  updated. It also reworks the logic and comments for pushing the
  writeback offset operand and r0 operand to clarify the logic:
  writeback offset needs to be pushed if it's a register writeback,
  r0 needs to be pushed if not and the instruction is a
  VLD1/VLD2/VST1/VST2.

This patch adds a utility function that works on any CFG, given its RPO
traversal and its LoopInfoBase. This function is a generalization
of isIrreducibleCFG  from lib/CodeGen/ShrinkWrap.cpp. The code in
lib/CodeGen/ShrinkWrap.cpp is also updated to use the new generic utility

[testsuite] Remove workaround for categories and inline tests.

Adding categories to inline tests does not work because the attribute
is set at the function level. For methods, this means it applies to all
instances of that particular class. While this is what we want in most
cases, it's not for inline tests, where different instances correspond
to different tests.

With the workaround in place, assigning a category to one test resulted
in the category applied to *all* inline tests.

This patch removes the workaround and throws an exception with an
informative error message, to prevent this from happening in the future.

6 years agobpf: introduce -mattr=dwarfris to disable DwarfUsesRelocationsAcrossSections

bpf: introduce -mattr=dwarfris to disable DwarfUsesRelocationsAcrossSections

Commit e4507fb8c94b ("bpf: disable DwarfUsesRelocationsAcrossSections")
disables MCAsmInfo DwarfUsesRelocationsAcrossSections unconditionally
so that dwarf will not use cross section (between dwarf and symbol table)
relocations. This new debug format enables pahole to dump structures
correctly as libdwarves.so does not have BPF backend support yet.

This new debug format, however, breaks bcc (https://github.com/iovisor/bcc)
source debug output as llvm in-memory Dwarf support has some issues to
handle it. More specifically, with DwarfUsesRelocationsAcrossSections
disabled, JIT compiler does not generate .debug_abbrev and Dwarf
DIE (debug info entry) processing is not happy about this.

This patch introduces a new flag -mattr=dwarfris
(dwarf relocation in section) to disable DwarfUsesRelocationsAcrossSections.
DwarfUsesRelocationsAcrossSections is true by default.

Set DF_TEXTREL to executables that need text relocations.

Summary:
If an executable needs text relocations, it should be marked as such so
that the loader can prepare for text relocations. We currently create a
dummy segment with DT_TEXTREL for that purpose.

Generic ABI as of 2000 [1] mentioned that "Its [DT_TEXTREL's] use
has been superseded by the DF_TEXTREL flag". However, it's actually not
superseded even after 18 years. OpenBSD and musl recognize only DT_TEXTREL.
So we still need to set both.

[NFC] Move CommentOpts checks to the call sites that depend on it.

When parsing comments, for example, for -Wdocumentation, slightly different
behaviour occurs when -fparse-all-comments is specified. However, these
differences are subtle:

 1. All comments are saved during parsing, regardless of whether they are doc
    comments or not.
 2. "Maybe-doc" comments, like //<, //!, etc, are saved as such, instead of
    marking them as ordinary comments. The maybe-doc type of comment is never
    saved otherwise. (Warning on these is the impetus of -Wdocumentation.)
 3. All comments are treated as doc comments in ASTContext, even if they are
    ordinary.

This change moves the logic for checking CommentOptions.ParseAllComments closer
to where it has an effect. The overall logic is unchanged, but checks of the
ParseAllComments flag are now done where the effect will be clearer.
