Craig Topper 8b6600363a [X86] Promote athlon, athlon-xp, k8, and k8-sse3 to types instead of subtypes in getHostCPUName. NFCI
This removes the athlon type and simplifies the string decoding. We only really need these type/subtype breaks where we need to match libgcc/compiler-rt and these CPUs aren't part of that.

I'm looking into moving some of this information to a .def file to share with clang's __builtin_cpu_is handling. And while these CPUs aren't part of that the less lines I have to deal with in the .def file the better.

Jake Ehrlich c3a89eefd6 Reland "Add support for writing 64-bit symbol tables for archives when offsets become too large for 32-bit"
Tests were failing because some bots were running out of address
space and memory. Additionally the test was very slow. These issues
were solved by changing the test to take advantage of sparse filse and
restricting the test to run only on 64-bit systems.

This should fix https://bugs.llvm.org//show_bug.cgi?id=34189

This change makes it so that if writing a K_GNU style archive, you need
to output a > 32-bit offset it should output in K_GNU64 style instead.

Jun Bum Lim 2a58933519 Add CallSiteSplitting pass
Summary:
This change add a pass which tries to split a call-site to pass
more constrained arguments if its argument is predicated in the control flow
so that we can expose better context to the later passes (e.g, inliner, jump
threading, or IPA-CP based function cloning, etc.).
As of now we support two cases :

1) If a call site is dominated by an OR condition and if any of its arguments
are predicated on this OR condition, try to split the condition with more
constrained arguments. For example, in the code below, we try to split the
call site since we can predicate the argument (ptr) based on the OR condition.

Split from :
      if (!ptr || c)
        callee(ptr);
to :
      if (!ptr)
        callee(null ptr)  // set the known constant value
      else if (c)
        callee(nonnull ptr)  // set non-null attribute in the argument

2) We can also split a call-site based on constant incoming values of a PHI
For example,
from :
      BB0:
       %c = icmp eq i32 %i1, %i2
       br i1 %c, label %BB2, label %BB1
      BB1:
       br label %BB2
      BB2:
       %p = phi i32 [ 0, %BB0 ], [ 1, %BB1 ]
       call void @bar(i32 %p)
to
      BB0:
       %c = icmp eq i32 %i1, %i2
       br i1 %c, label %BB2-split0, label %BB1
      BB1:
       br label %BB2-split1
      BB2-split0:
       call void @bar(i32 0)
       br label %BB2
      BB2-split1:
       call void @bar(i32 1)
       br label %BB2
      BB2:
       %p = phi i32 [ 0, %BB2-split0 ], [ 1, %BB2-split1 ]

This commit implements the semicolon insertion logic into the extract
refactoring. The following rules are used:

- extracting expression: add terminating ';' to the extracted function.
- extracting statements that don't require terminating ';' (e.g. switch): add
  terminating ';' to the callee.
- extracting statements with ';':  move (if possible) the original ';' from the
  callee and add terminating ';'.
- otherwise, add ';' to both places.

Kostya Kortchinsky 8acdc98271 [Driver] Add Scudo as a possible -fsanitize= option
Summary:
This change adds Scudo as a possible Sanitizer option via -fsanitize=.
This allows for easier static & shared linking of the Scudo library, it allows
us to enforce PIE (otherwise the security of the allocator is moot), and check
for incompatible Sanitizers combo.

In its current form, Scudo is not compatible with any other Sanitizer, but the
plan is to make it work in conjunction with UBsan (-fsanitize=scudo,undefined),
which will require additional work outside of the scope of this change.

DenseMap does not provide deterministic iteration order so with that

leading to random order of the blocks in the predecessor lists.

Without this change, I get the same predecessor order in about 90% of the
time when I compile a certain reproducer and in 10% I get a different one.

No idea how to make a proper test case for this.

When the clangd.applyFix command is handled on the server, it can send a

the client doesn't explicitly have to know how to handle
clangd.applyFix. Therefore, the code to handle clangd.applyFix in the VS
Code extension (and any other Clangd client) is not required anymore.

Diana Picus d1b618177a [globalisel][tablegen] Skip src child predicates
The GlobalISel TableGen backend didn't check for predicates on the
source children. This caused it to generate code for ARM patterns such
as SMLABB or similar, but without properly checking for the sext_16_node
part of the operands. This in turn meant that we would select SMLABB
instead of MLA for simple sequences such as s32 + s32 * s32, which is
wrong (we want a MLA on the full operands, not just their bottom 16
bits).

This patch forces TableGen to skip patterns with predicates on the src
children, so it doesn't generate code for SMLABB and other similar ARM
instructions at all anymore. AArch64 and X86 are not affected.
