[Lldb-commits] [lldb] [LLDB] Define _BSD_SOURCE globally, to get optreset available in mingw's getopt.h (PR #76137)
https://github.com/mstorsjo created https://github.com/llvm/llvm-project/pull/76137 We previously were defining _BSD_SOURCE right before including getopt.h. However, on mingw-w64, getopt.h is also transitively included by unistd.h, and unistd.h can be transitively included by many headers (recently, by some libc++ headers). Therefore, to be safe, we need to define _BSD_SOURCE before including any header. Thus do this in CMake. This fixes https://github.com/llvm/llvm-project/issues/76050.

LOG: [lldb] Add actionable feedback when overwriting a command fails (#76030)
If adding a user commands fails because a command with the same name
already exists, we only say that "force replace is not set" without
telling the user _how_ to set it. There are two ways to do so; this
commit changes the error message to mention both.

Subject: [PATCH 1/4] Problem :For Kernel Modules ,emitting the relocs like
R_X86_64_REX_GOTPCRELX for the OPENMP internal vars like
https://godbolt.org/z/hhh7ozojz.
Solution : Mark the OpenMP internal variables with dso_local
conditionally for no-pic and no-pie ,then
a)reset the dso_local for thread_local and weak linkage vars.

Subject: [PATCH 2/3] 1) Since the{if(x == e) {x = v;} else {d = x;}}
results in generation of cmpxchg in the LLVM IR, the memory order clause in
"fail" clause is now being added.In case of other operators ">" & "<"
e.g.dx = dx > de ? de : dx; result in atomicrmw in the LLVM IR.
"atomicrmw" can have only one memory order clause. Currently, the memory
order clause is ignored. 2) Test cases for codegen 3) In SemaOpenMP.cpp,
addedEncounteredAtomicKinds.contains(OMPC_compare) instead of AtomicKind
== OMPC_compare. This was to accomodate where AtomicKind is OMPC_capture.

I'm not sure how hot this code path is, but we are doing a bunch of unnecessary
string copies in here (as we were before this PR as well...). For example,
`message` and `severity` are both `StringRef`s that don't need to be converted
into strings.
Suggestion:
```c++
std::string DiagnosticManager::GetString(char separator) {
std::string ret;
llvm::raw_string_ostream stream(ret);
for (const auto &diagnostic : Diagnostics()) {
llvm::StringRef severity = StringForSeverity(diagnostic->GetSeverity());
stream << severity;
llvm::StringRef message = diagnostic->GetMessage();
std::string searchable_message = message.lower();
auto severity_pos = message.find_first_of(severity);
stream << message.take_front(severity_pos);
if (severity_pos != llvm::StringRef::npos)
stream << message.drop_front(severity_pos + severity.size());
stream << separator;
}

[Lldb-commits] [lldb] [lldb] Remove redundant severity substring within a diagnostic message. (PR #76111)
https://github.com/felipepiovezan commented: I'll leave the approval to others, but I left a coding suggestion. It would be a lot nicer if we could tell the producer of those messages to not include the severity, but I think this is way out of scope here. The "severity" inside the message is likely coming from a producer that is too far gone at this point. https://github.com/llvm/llvm-project/pull/76111 ___ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits

Subject: [PATCH 1/4] Problem :For Kernel Modules ,emitting the relocs like
R_X86_64_REX_GOTPCRELX for the OPENMP internal vars like
https://godbolt.org/z/hhh7ozojz.
Solution : Mark the OpenMP internal variables with dso_local
conditionally for no-pic and no-pie ,then
a)reset the dso_local for thread_local and weak linkage vars.

You may get a few more messages as other builders get to it (the Mac ones mainly), if it's a link error with `lldbPluginProcessWindowsCommon` then it's already been fixed and you can ignore it.

That would be something like
```
int internal_fork(void) {
// Call syscall directly to avoid pthread_atfork handler processing.
//
// This is highly unportable on Solaris since syscalls are an implementation
// detail subject to change.
return syscall(SYS_forksys, 0, 0);
}
```
Unfortunately, this fails miserably: at least every asan test that invokes the
`llvm-symbolizer` fails like
```

--inlines --default-arch=i386
==4031==Waiting on the process failed (errno 10).

So I'd say making the highlight stuff into a struct is one PR, then adding function highlighting is another. Makes it easier to understand for everyone involved. On tests for function highlighting, assuming we know that `PutCStringHighlighted` works (which we do), we don't need to repeat single match, multiple match, end of string match, etc. for functions as well. Just check that the parts of the output for functions have some sort of highlight in them. Use the simplest query that will achieve that. https://github.com/llvm/llvm-project/pull/76112 ___ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits

Subject: [PATCH 2/3] 1) Since the{if(x == e) {x = v;} else {d = x;}}
results in generation of cmpxchg in the LLVM IR, the memory order clause in
"fail" clause is now being added.In case of other operators ">" & "<"
e.g.dx = dx > de ? de : dx; result in atomicrmw in the LLVM IR.
"atomicrmw" can have only one memory order clause. Currently, the memory
order clause is ignored. 2) Test cases for codegen 3) In SemaOpenMP.cpp,
addedEncounteredAtomicKinds.contains(OMPC_compare) instead of AtomicKind
== OMPC_compare. This was to accomodate where AtomicKind is OMPC_capture.

Subject: [PATCH 1/3] [LLDB] Fix write permission error in
TestGlobalModuleCache.py
TestGlobalModuleCache.py, a recently added test, tries to update
a source file in the build directory, but it assumes the file is
writable. In our distributed build and test system, this is not
always true, so the test often fails with a write permissions error.
This change fixes that by setting the permissions on the file to
be writable before attempting to write to it.

The one from `DiagnosticManager.h` is its `Dump()` method which itself has 7

I have a future PR that'll move this functionality into `class Status`, and
whatever we decided to do here we can do there as well.

A StringRef is a _non-owning view_ into a string. When we see one of those,
that means the author of the code is making a few promises:
1. They don't need to mutate the string
2. They don't need to extend its lifetime past "the current" context.
Conversely, when the author conjures a `std::string` out of `StringRef`, the
author is saying that they intend to break one of those promises. Note that
your code doesn't need to, with the exception `searchable_message`: we had to
modify the string with "to_lower"!

Author: Martin Storsjö Date: 2023-12-22T00:40:12+02:00 New Revision: f70b229e9643ddb895d491b62a5ec0655917f6f8 URL: https://github.com/llvm/llvm-project/commit/f70b229e9643ddb895d491b62a5ec0655917f6f8 DIFF: https://github.com/llvm/llvm-project/commit/f70b229e9643ddb895d491b62a5ec0655917f6f8.diff LOG: [LLDB] Define _BSD_SOURCE globally, to get optreset available in mingw's getopt.h (#76137) We previously were defining _BSD_SOURCE right before including getopt.h. However, on mingw-w64, getopt.h is also transitively included by unistd.h, and unistd.h can be transitively included by many headers (recently, by some libc++ headers). Therefore, to be safe, we need to define _BSD_SOURCE before including any header. Thus do this in CMake. This fixes https://github.com/llvm/llvm-project/issues/76050.

Subject: [PATCH 1/2] [RegAllocFast] Refactor dominates algorithm for large
basic block
The original brute force dominates algorithm is O(n) complexity so it is
very slow for very large machine basic block which is very common with
O0. This patch added InstrPosIndexes to assign index for each
instruction and use it to determine dominance. The complexity is now
O(1).

Subject: [PATCH 1/2] [RegAllocFast] Refactor dominates algorithm for large
basic block
The original brute force dominates algorithm is O(n) complexity so it is
very slow for very large machine basic block which is very common with
O0. This patch added InstrPosIndexes to assign index for each
instruction and use it to determine dominance. The complexity is now
O(1).
