[llvm-bugs] [Bug 48294] New: Crash with __builtin_memcpy_inline when source is an array
https://bugs.llvm.org/show_bug.cgi?id=48294
Bug ID: 48294
Summary: Crash with __builtin_memcpy_inline when source is an
array
Product: clang
Version: 11.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: jasper.matts...@gmail.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

Created attachment 24208
--> https://bugs.llvm.org/attachment.cgi?id=24208&action=edit
Full backtrace from crash
__builtin_memcpy_inline uses custom type checking, and thus does not perform
default argument conversions. Basically, I invoked the builtin with a pointer
and an array as its arguments, expecting array-to-pointer decay to happen.
Instead, Clang crashed as codegen.
I'm not sure if default conversions should happen with __builtin_memcpy_inline,
but it probably should not crash.
Example code:
int main() {
char to, from[1];
__builtin_memcpy_inline(&to, from, 1);
}
Snippet from backtrace:

https://bugs.llvm.org/show_bug.cgi?id=48301 Bug ID: 48301 Summary: [Mips] Fix test emergency-spill-slot-near-fp.ll Product: libraries Version: trunk Hardware: PC OS: Windows NT Status: NEW Severity: enhancement Priority: P Component: Backend: MIPS Assignee: unassignedb...@nondot.org Reporter: paul_robin...@playstation.sony.com CC: llvm-bugs@lists.llvm.org After applying https://reviews.llvm.org/D91734 the test llvm/test/CodeGen/Mips/emergency-spill-slot-near-fp.ll began failing. The test uses a long sequence of volatile loads and stores to try to create enough register pressure to trigger the use of the "emergency spill slot" which appears to be at 0(fp). With the above patch, register usage changed enough that this spill slot wasn't required. I tried adding more loads and stores, but that just caused a normal spill and reload. Rather than have this one test block the patch, @rnk proposed that I mark it XFAIL and file this bug. I'll commit D91734 shortly, and post the git hash here. -- You are receiving this mail because: You are on the CC list for the bug.___ llvm-bugs mailing list llvm-bugs@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs

Bug ID: 48305
Summary: clang-format mismatches braces with nested unnamed
scopes
Product: clang
Version: 11.0
Hardware: PC
OS: Linux

Severity: normal

Hello.
With clang-format -10 and -11 installed from repo on ubuntu 20.11 following c++
code is obviously formatted wrong:
```
clang-format-11 -style=llvm test.cpp
void foo() {
{// asdf
{int a;
}
}
{
{ int b; }
}
}
```
Removing `{// asdf` is sufficient to format it ok.
I expect it to be formatted like this (possibly with comment in new line, but
this may be llvm style):
```
void foo() {
{// asdf
{ int a; }
}
{
{ int b; }
}
}
```

PR48150 LoopLoadElim may end up expanding an AddRec from a loop which is not the current loop. This loop may not be in simplify form. We figure it out after the no-return point, so cannot bail in this case. AddRec requires simplify form to expand. The only way to ensure this does not crash is to simplify all loops beforehand.
