Test case for in-scope variable openmp bug
Overview:
A debugger (either lldb or gdb) is unable to access certain in-scope variables
from within an OpenMP parallel region. I've attached the test case that I've
written for GDB's test suite. I could shortened this program for bug reporting
purposes, but ultimately it's worth considering each parallel region in this
file because each of these regions will likely show additional problems with
debugging in-scope variables.
I've tried clang 8 thru 10.0.0; each of these versions are broken.
In the examples below, s1, s3, and i3 are all in scope and should be printable
by the debugger, but are not.
I wanted to use clang 10.0.0 which is found in recent Fedora Rawhide. These
same problems are also present on Fedora 31 and earlier which use earlier
versions of clang.
Steps to reproduce:
[kev@rawhide-1 tmp]$ clang --version
clang version 10.0.0 (Fedora 10.0.0-0.1.rc1.fc32)
Target: x86_64-unknown-linux-gnu

GDB is able to print values for s1 and s3, but they are incorrect. (I haven't
investigated where they're coming from.) Also note that gdb can't find a value
for i3.

I bisected this to
https://github.com/llvm/llvm-project/commit/907cefe721437fa8950c1b6c1c028038b175f921,
so it's a regression in 10.0. gcc, MSVC and Clang 9 all accept this code:
https://godbolt.org/z/TfZBf2
Clang trunk does compile this if I explicitly instantiate the parent class, but
I don't believe that should be necessary, i.e. if I change the body of
tuple_wrapper::get to
return get0<0, Ts...>(tuple(*this));

This method of building is extremely slow compared with building with ninja. I tried to follow these instructions naively and the build was so slow that, after waiting about an hour it still self-reported about 12% progress. After running "cmake -DLLVM_ENABLE_PROJECTS=clang -G Ninja ../llvm", and then building with ninja, the entire build took at most 15 minutes. Is it possible to at least describe both configurations so that readers don't have to find and fix the issues with make on their own? -- 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

Given the following test case:
//
// typedef.cpp
//
int bar(float Input) { return (int)Input; }
unsigned foo(char Param) {
typedef int INT;
INT Value = Param;
{
typedef float FLOAT;
{
FLOAT Added = Value + Param;
Value = bar(Added);
}
}
return Value + Param;
}
//
Using the following command line options to generate debug info
(DWARF) and (COFF):
clang -c -g -O0 typedef.cpp -o typedef.o
clang -c -g -O0 typedef.cpp -o typedef-coff.o -gcodeview
--target=x86_64-windows
Looking at the output generated by llvm-dwarfdump and llvm-diva,
the debug info shows the typedefs 'INT'and 'FLOAT' to be at the same lexical
scope (function scope).

[llvm-bugs] [Bug 44883] New: Losing a global const int in clang++
https://bugs.llvm.org/show_bug.cgi?id=44883
Bug ID: 44883
Summary: Losing a global const int in clang++
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org

CC: blitzrak...@gmail.com, dgre...@apple.com,
erik.pilking...@gmail.com, llvm-bugs@lists.llvm.org,
richard-l...@metafoo.co.uk
I'm having a bizarre issue that I suspect is my fault, but I am running out of
ideas on why. Sorry for wasting your time but can you please explain this to
me:
$ cat a.cc
const int foo = 23;
$ cat b.cc
extern const int foo;
int main() { return foo; }
$
First issue:
$ nm b.o
U foo
T main
$
OK I see why main is not mangled. But foo should be mangled, no?
Doing extern "C++" const int foo does not help, still not mangled.
Second issue:
$ nm a.o
$
Nothing. What happened to foo?
Renaming the files to a.c and b.c makes things work.
Have I missed a C++ memo or two here?
I tried this with GCC too, and g++ will generate a mangled foo symbol in a.o
(_ZL3foo) but it will generate a reference to unmangled foo in b.o. I filed a
bug with them, too.

Crucially, incorrect locations under safestack are being generated even at -O0, which is a fairly bad failure. For a clean merge, these commits depend on the cherry pick in bug 44814.

Spun off from bug 39724, Davides test case which I copy below has 'l' optimised
out in the fn1 function. The cause appears to be a DAGCombine that drops the
multiply, which the SelectionDAG salvager can't recover. This is true of todays
master, 2733ad2c24 ish.
8<
a.c:
extern void other_func(long int, long int, long int);
__attribute__((noinline))
int fn1 (long int x, long int y, long int z) {
int l = x * 2;
int q = y * z;
other_func(x, y, z);
return l + q;
}
__attribute__((noinline)) long int
fn2 (long int a, long int b, long int c)
{
long int q = 2 * a;
return fn1 (5, 6, 7);
}
int main(void) {
return fn2(14, 23, 34);
}
b.c:
void other_func(long int a, long int b, long int c) {}
built with: ${CC} a.c b.c -O3 -g
>8
I guess this ticket can more broadly represents the fact that all the folding /
morphing in DAGCombine isn't robustly salvaged.

[llvm-bugs] [Bug 44880] New: Debug invariance in GlobalOpt
https://bugs.llvm.org/show_bug.cgi?id=44880
Bug ID: 44880
Summary: Debug invariance in GlobalOpt
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org

Created attachment 23121
--> https://bugs.llvm.org/attachment.cgi?id=23121&action=edit
IR reproducer.
After the introduction of "[InstCombine][DebugInfo] Fold constants wrapped in
metadata", some debug invariance started appearing.
Please note that that commit was reverted in
982944525c7706c4dee00042d5b7cf2f0d87804f due to this issue.
C reproducer:
int a, b, c;
static int arr[4];
void foo() {
const int *e[] = {&arr[2]};
const int **f = &e[0];
c = f != foo;
}
int main() {
for (b = 0; b < 4; b++)
a = a ^ arr[b];
return 0;
}
Commands:
$ clang -O3 -g globalopt.c -S -o - -mllvm -disable-debug-info-print -o
with-debug.s
$ clang -O3 globalopt.c -S -o - -mllvm -disable-debug-info-print -o
without-debug.s
$ diff -u without-debug.s with-debug.s

+ xorlarr+12(%rip), %eax
+ movl%eax, a(%rip)
movl$4, b(%rip)
xorl%eax, %eax
retq
That commit appears to have exposed a pre-existing debug invariance issue in
GlobalOpt.
This can also be reproduced by just running GlobalOpt on the attached IR
reproducer.
$ opt -strip-debug globalopt.ll | opt -S -globalopt -o without-debug.ll
$ opt globalopt.ll | opt -S -globalopt -strip-debug -o with-debug.ll

i64 0, i64 3), align 4
+ %xor.3 = xor i32 %3, %xor.2
The issue seems to be that the dbg.value intrinsic:
call void @llvm.dbg.value(metadata i64 ptrtoint (i32* getelementptr inbounds
([4 x i32], [4 x i32]* @arr, i64 0, i64 2) to i64), metadata !24, metadata
!DIExpression()), !dbg !32
seems to lead to GlobalStatus::analyzeGlobal() returning true that @arr has its
address taken. This seems to have to do with the analysis bailing out due to
the ptrtoint use of the GEP:
// If the result of the constantexpr isn't pointer type, then we won't
// know to expect it in various places. Just reject early.
if (!isa(CE->getType()))
return true;
