Comparing the parent PID with 1 isn't sufficient to ensure the parent is alive,
because of prctl(PR_SET_CHILD_SUBREAPER, ...). Compare with the real parent's
recorded PID instead.

Code cleanup: rename VTableContext to ItaniumVTableContext, VTableBuilder to ItaniumVTableBuilder and clang-format code around

Substantial SelectionDAG scheduling is going away soon, and is
interfering with Hao's attempts to implement LDn/STn instructions, so
I say we make the leap first.

There were a few reorderings (inevitably) which broke some tests. I
tried to replace them with CHECK-DAG variants mostly, but some too
complex for that to be useful and I just reordered them.

This change removes code in various places which was setting the File Ordinals.
This is because the file ordinals are assigned by the way files are resolved.

There was no other way than making the getNextFileAndOrdinal be set const and
change the _nextOrdinal to mutable.

There are so many places in code, that you would need to cleanup to make
LinkingContext non-const!

This was only working because AVX had cheaper rules in all cases.
I'm sure there are other places in this file where predicates are missing.

Replace a couple instructions with patterns referring to other instructions with same encoding and operands. Mark a couple other instructions as CodeGenOnly since we have FR and VR instructions and only one of them is needed by the assembler/disassembler.

Will fix this in later commits. Not sure why the regex is not passing.

llvm-svn: 192273

Use AVX512PIi8 for the alt forms of vcmp instructions. This adds the TB prefix and keeps the mnemonic from starting with an extra 'v'

llvm-svn: 192272

Mark some instructions as CodeGenOnly since they aren't needed by the assembler or disassembler. Disassembler already filtered them, but asm parser still had them in its tables.

This associates resolveState to FileNodes. The control node derive
their resolution state from the inputElements that are contained in
it.

This makes --start-group/--end-group to work with ELF linking.

Add in64BitMode/in32BitMode to the MMX/SSE2/AVX maskmovq/dq instructions. This way the asm parser will pick the right one based on the mode. Instruction selection already did the right thing based on the pointer size.

Use 32-bit register enums without gaps on 64-bit hosts.
Don't show 64-bit registers when debugging 32-bit targets.
Add psuedo gpr registers (ax, ah, al, etc.)
Add mmx registers.
Fix TestRegisters.py to not read ymm15 register on 32-bit targets.
Fill out and move gcc/dwarf/gdb register enums to RegisterContext_x86.h

Constant ValueObjects should clear their description as well as their summary. Rationale being that both can depend on deeper-than-constified data
so both are subject to changes in "unpredictable" ways
To see this consider repeatedly po'ing a persistent variable of a type whose -description result changes at each invocation

An invalid decltype expression like 'decltype int' gives:
error: expected '(' after 'decltype'

This makes it so 'sizeof int' gives a similar one:
error: expected parentheses around type name in sizeof expression

DICompositeType is updated to use DIScopeRef.

Paired commit with r192256.

A paired commit at clang is required due to changes to DIBuilder.
