Med Ismail Bennani [Sat, 4 Mar 2023 02:52:15 +0000 (18:52 -0800)]
[lldb] Extend SWIG SBProcess interface with WriteMemoryAsCString method

This patch tries to address an interoperability issue when writing
python string into the process memory.

Since the python string is not null-terminated, it would still be
written to memory however, when trying to read it again with
`SBProcess::ReadCStringFromMemory`, the memory read would fail, since
the read string doens't contain a null-terminator, and therefore is not
a valid C string.

To address that, this patch extends the `SBProcess` SWIG interface to
expose a new `WriteMemoryAsCString` method that is only exposed to the
SWIG target language. That method checks that the buffer to write is
null-terminated and otherwise, it appends a null byte at the end of it.

[RISCV][llvm-tblgen] Support conditional definitions using !exists clauses

The core part of this change is an extension to the tablegen language to allow conditional definition of records using if-statements based on !exists conditions.

The RISCV td file change is mostly to illustrate the potential use of conditional definitions. I am deliberately not maximally simplifying in this change to make merging with downstream code (or simply rebasing while this on review) easier.

Some background to make the change understandable.

TableGen does not have an if statement internally. It has if expressions - in the form of TernInitOp with IF opcode - and foreach statements. It implements an if-statement as a foreach which iterates either 0 or 1 times.

Foreach nodes are then evaluated via unrolling inside the parser. Specifically, they are evaluated, at latest, when the outermost multiclass or loop containing them reaches end of scope. The unrolled statements remain (potentially) unresolved after unrolling, but the number of iterations must be known at this point.

An !exists clause can only evaluate at final evaluation. (Specifically, forward references to definitions are allowed - up to the end of the containing scope at least.) The existing code did not set the final flag on the resolver, and thus would leave the !exists clause in an unresolved state. This would then cause an error since we don't know how many iterations on which to unroll the (synthetic) foreach loop.

I chose to only finally-evaluate the condition of the if-expression. This allows us to pick an arm at scope exit without inhibiting definitions in the arm from having self references.

Recommit [C++20] [Modules] Trying to compare the trailing require clause from the primary template function

Close https://github.com/llvm/llvm-project/issues/60890.

For the following example:

```
export module a;

export template<typename T>
struct a {
friend void aa(a) requires(true) {
}
};
```

```
export module b;

struct c {

aa(a<int>());
}
};
```

```
import a;
import b;
import c;

void d() {
aa(a<int>());
}
```

The current clang will reject this incorrectly. The reason is that the
require clause  will be replaced with the evaluated version
(https://github.com/llvm/llvm-project/blob/efae3174f09560353fb0f3d528bcbffe060d5438/clang/lib/Sema/SemaConcept.cpp#L664-L665).
In module 'b', the friend function is instantiated but not used so the
require clause of the friend function is `(true)`. However, in module
'c', the friend function is used so the require clause is `true`. So
deserializer classify these two function to two different functions
instead of one. Then here is the bug report.

The proposed solution is to try to compare the trailing require clause
of the primary template when performing ODR checking.

[CodeGen] guarantee templated static variables are initialized in the reverse instantiation order

Based on Richard's suggestion in D126341:
`If we can actually describe a rule that we provide for initialization
order of instantiated variables, and we can easily implement that rule
and be confident we won't want to substantially weaken it later, and we
can thereby assure our users that we will satisfy that rule, then I
think that could be interesting, but anything less than that doesn't
seem worthwhile to me.`

I'm giving it try here. IMHO the implementation is pretty simple and
does not change behavior for unrelated constructs like the timing when
instantiated variables are passed to CodeGen.

This is based on the same ordering guarantee needed for inline variables D127233.
To provide this guarantee, we also need to
emit DeferredDeclsToEmit in the DFS order. https://github.com/llvm/llvm-project/commit/e5df59ff78faebd897e81907606ce6074aac0df6
originally supported this but it is not exactly DFS order for cases like
the one in cwg362. For the example of Fib<5>, it triggers the instantiation
of Fib<4> and Fib<3>. However, due to the way GlobalEagerInstantiationScope
is implemented, Fib<4> does not actually trigger Fib<3> instantiation
since it is already triggered by Fib<5>. This breaks the guarantee.

This patch makes sure DeferredDeclsToEmit is emitted in DFS order by moving
DeferredDeclsToEmit storage from the call stack to an explicit stack-like
data structure. Then the DFS order could be enforced.

[C++20] [Modules] Deprecate to load C++20 Modules eagerly

Close https://github.com/llvm/llvm-project/issues/60824

The form -fmodule-file=<path-to-BMI> will load modules eagerly and the
form -fmodule-file=<module-name>=<path-to-BMI> will load modules lazily.
The inconsistency adds many additional burdens to the implementations.
And the inconsistency looks not helpful and necessary neither. So I want
to deprecate the form -fmodule-file=<path-to-BMI> for named modules.
This is pretty helpful for us (the developers).

Does this change make any regression from the perspective of the users?

To be honest, yes. But I think such regression is acceptable. Here is
the example:

```
// M.cppm
export module M;
export int m = 5;

// N.cpp
// import M; // woops, we forgot to import M.
int n = m;
```

In the original version, the compiler can diagnose the users to import
`M` since the compiler have already imported M. But in the later style,
the compiler can only say "unknown identifier `m`".

But I think such regression doesn't make a deal since it only works if
the user put `-fmodule-file=M.pcm` in the command line. But how can the
user put `-fmodule-file=M.pcm` in the command line without `import M;`?
Especially currently such options are generated by build systems. And
the build systems will only generate the command line from the source
file.

So I think this change is pretty pretty helpful for developers and
almost innocent for users and we should accept this one.

I'll add the release notes and edit the document after we land this.

16 months agoAdd the ability to segment GSYM files.
Greg Clayton [Thu, 9 Feb 2023 18:16:34 +0000 (10:16 -0800)]
Add the ability to segment GSYM files.

Some workflows can generate large GSYM files and sharding GSYM files into segments can help some performant workflows that can take advantage of smaller GSYM files. This patch add a new --segment-size option to llvm-gsymutil. This option can specify a rough size in bytes of how large each segment should be.

Segmented GSYM files contain only the strings and files that are needed for the FunctionInfo objects that are added to each shard. The output file path gets the first address of the first contained function info appended as a suffix to the filename. If a base address of an image is set in the GsymCreator, then all segments will use this same base address which allows lookups for symbolication to happen correctly when the image has been slid in memory.

Code has been addeed to refactor and re-use methods within the GsymCreator to allow for segments to be created easily and tested.

Example of segmenting GSYM files:
