2 years ago[AsmParser] Rework logic around "region argument parsing"
Chris Lattner [Tue, 26 Apr 2022 19:03:03 +0000 (12:03 -0700)]
[AsmParser] Rework logic around "region argument parsing"

The asm parser had a notional distinction between parsing an
operand (like "%foo" or "%4#3") and parsing a region argument
(which isn't supposed to allow a result number like #3).

Unfortunately the implementation has two problems:

1) It didn't actually check for the result number and reject
   it.  parseRegionArgument and parseOperand were identical.
2) It had a lot of machinery built up around it that paralleled
   operand parsing.  This also was functionally identical, but
   also had some subtle differences (e.g. the parseOptional
   stuff had a different result type).

I thought about just removing all of this, but decided that the
missing error checking was important, so I reimplemented it with
a `allowResultNumber` flag on parseOperand.  This keeps the
codepaths unified and adds the missing error checks.

Yitzhak Mandelbaum [Wed, 27 Apr 2022 17:21:59 +0000 (17:21 +0000)]
[clang][dataflow] Perform structural comparison of indirection values in `join`.

This patch changes `Environment::join`, in the case that two values at the same
location are not (pointer) equal, to structurally compare indirection values
(pointers and references) for equivalence (that is, equivalent pointees) before
resorting to merging.

This change makes join consistent with equivalence, which also performs
structural comparison. It also fixes a bug where the values are `ReferenceValue`
but the merge creates a non-reference value. This case arises when the
`ReferenceValue`s were created to represent an lvalue, so the "reference-ness"
is not reflected in the type. In this case, the pointees will always be
equivalent, because lvalues at the same code location point to the location of a
fixed declaration, whose location is itself stable across blocks.

We were unable to reproduce a unit test for this latter bug, but have verified
the fix in the context of a larger piece of code that triggers the bug.

64-bit mode or a DWORD or WORD symbol is passed in 32-bit mode, then
MSVC's assembler recognizes that as an indirect call. Additionally, if
the operand is qualified as a ptr, then that should also be an indirect
call.

Furthermore, in 64-bit mode, such operands are implicitly rip-relative
(in fact, MSVC's assembler ml64.exe does not allow explicitly specifying
rip as a base register.)

To keep this patch managable, this patch does not include:
* error messages for wrong operand types (e.g. passing a QWORD in 32-bit
  mode)
* resolving indirect calls if the symbol is declared after it's first
  use (llvm-ml currently only runs a single pass).
* imlementing the extern keyword (required to resolve

[lldb] Add FixAnyAddress to ABI plugins

FixAnyAddress is to be used when we don't know or don't care
whether we're fixing a code or data address.

By using FixAnyAddress over the others, you document that no
specific choice was made.

On all existing platforms apart from Arm Thumb, you could use
either FixCodeAddress or FixDataAddress and be fine. Up until
now I've chosen to use FixDataAddress but if I had
chosen to use FixCodeAddress that would have broken Arm Thumb.

Hence FixAnyAddress, to give you the "safest" option when you're
in generic code.

Uses of FixDataAddress in memory region code have been changed
to FixAnyAddress. The functionality is unchanged.

[Flang] Initial lowering of the Fortran Do loop

This patch adds code to lower simple Fortran Do loops with loop control.
Lowering is performed by the the `genFIR` function when called with a
`Fortran::parser::DoConstruct`. `genFIR` function calls `genFIRIncrementLoopBegin`
then calls functions to lower the body of the loop and finally calls
the function `genFIRIncrementLoopEnd`. `genFIRIncrementLoopBegin` is
responsible for creating the FIR `do_loop` as well as storing the value of
the loop index to the loop variable. `genFIRIncrementLoopEnd` returns
the incremented value of the loop index and also stores the index value
outside the loop. This is important since the loop variable can be used
outside the loop. Information about a loop is collected in a structure
`IncrementLoopInfo`.

Note 1: Future patches will bring in lowering for unstructured,
infinite, while loops
Note 2: This patch is part of upstreaming code from the fir-dev branch of
https://github.com/flang-compiler/f18-llvm-project.

[GVN] Encode GEPs in offset representation

When using opaque pointers, convert GEPs into offset representation
of the form P + V1 * Scale1 + V2 * Scale2 + ... + ConstantOffset.
This allows us to recognize equivalent address calculations even if
the GEPs don't use the same source element type.

This fixes an opaque pointer codegen regression seen in rustc.

[lldb] Fix escaping when launching in terminal with AppleScript

Fix escaping when launching in terminal with AppleScript. The invocation
we're building up is wrapped in single quotes when passed to bash and
wrapped in double quotes for AppleScript.

Here's an example invocation with the new escaping:

  tell application "Terminal"
    activate
          do script "/bin/bash -c 'arch -arch arm64 'darwin-debug'
            --unix-socket=/tmp/dL2jSh --arch=arm64 --working-dir
            \"/private/tmp/with spaces\" --disable-aslr --  \"foo\"
            \"bar\" \"baz\" ; echo Process exited with status $?';exit"
  end tell

Previously we were using unescaped single quotes which resulted in the
whole bash invocation being passed in pieces. That works most of the
time but breaks when you have a space in your current working directory
for example.
