[llvm-bugs] [Bug 37492] New: Type merging in some PDBs results in bad pointer typedefs
https://bugs.llvm.org/show_bug.cgi?id=37492 Bug ID: 37492 Summary: Type merging in some PDBs results in bad pointer typedefs Product: lld Version: unspecified Hardware: PC OS: Windows NT Status: NEW Severity: enhancement Priority: P Component: COFF Assignee: unassignedb...@nondot.org Reporter: amcca...@google.com CC: llvm-bugs@lists.llvm.org The type records for some typedefs, like `std::vector::const_pointer`, sometimes do not have the correct pointee type. It should be `const unsigned char`, but it's a bitfield. Similar problem for `const_reference` and `std::array`. Discovered in the webview.dll.pdb from a debug Chrome build. You can observe the problem by running `llvm-pdbutil pretty -types webview.dll.pdb`, which will effective assert on the bad type. If you use `dump -types`, you can manually follow the type IDs to an `LF_BITFIELD`. This does not happen for all PDBs. Here are some excerpts to illustrate: ``` 0x3E25 | LF_CLASS [size = 124] `std::vector >` unique name: `.?AV?$vector@EV?$allocator@E@std@@@std@@` vtable: , base list: , field list: 0x3E24 options: contains nested class | has unique name ``` If we look in the field list for 0x3E24, we find: ``` - LF_NESTTYPE [name = `const_pointer`, parent = 0x27F1] ``` Following the parent: ``` 0x27F1 | LF_POINTER [size = 12] referent = 0x22C6, mode = pointer, opts = None, kind = ptr32 ``` And finally, the referent leads to: ``` 0x22C6 | LF_BITFIELD [size = 12] type = 0x0020 (unsigned char), bit offset = 0, # bits = 1 ``` -- You are receiving this mail because: You are on the CC list for the bug.___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs

https://bugs.llvm.org/show_bug.cgi?id=37483 Artem Belevich changed: What|Removed |Added Resolution|--- |WONTFIX Status|NEW |RESOLVED --- Comment #2 from Artem Belevich --- I can reproduce it on sm_60. Jonas appears to be correct and that's a problem with ptxas in CUDA-8. PTX generated by clang is identical for both CUDA-8 and CUDA-9. However, SASS generated by ptxas is noticeably different. With CUDA-9 the code is very straightforward and you can see two writes, 8 bytes apart, both with the same value. With CUDA-8, func3 messes up the store to *l_302 and writes zero to the should_not_change field instead. ptxas in cuda-8 is known to have number of unfixed issues. So does ptxas in older cuda-9.x releases. I would suggest updating to more recent CUDA version or, consider replacing ptxas with the one from CUDA-9.1 (though you will not be able to compile for sm_20 if you do) -- You are receiving this mail because: You are on the CC list for the bug.___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs

Summary: wasm32: Codegen bug at O2 for llc
Product: libraries

Status: NEW
Severity: enhancement
Priority: P
Component: Backend: WebAssembly
Assignee: unassignedb...@nondot.org

IR
Originally reported at https://github.com/rust-lang/rust/issues/50754 I've
reduced the test case to a smaller piece of Rust code
(https://gist.github.com/4b0396c7599d3b15dadc2c82f62b624e) which at `-C
opt-level=2` for the Rust compiler generates the attached IR.
When the attached IR is compiled to a wasm object file with O0 it generates a
different answer than when generated with O2:
$ llc bar.ll -filetype=obj -O0 -o bar.o
$ wasm-ld bar.o -o bar.wasm --no-entry
$ node bar.js
0
$ llc bar.ll -filetype=obj -O2 -o bar.o
$ wasm-ld bar.o -o bar.wasm --no-entry
$ node bar.js
65534
where `bar.js` looks like:
const fs = require('fs');
let buf = fs.readFileSync('bar.wasm');
let m = new WebAssembly.Module(buf);
let inst = new WebAssembly.Instance(m, {});
console.log(inst.exports.test());
I unfortunately haven't been able to track this down much farther, but I was
hoping that y'all could help me reduce from here!

[llvm-bugs] [Bug 37487] New: Using std::__throw_bad_weak_ptr can produce invalid RTTI for std::runtime_error

test case that trigger the bug
I have encountered a miscompile for cuda program with clang 6.0 , with
optimization '-O1'and disappear with '-O2' and '-O3'.
I have reduced the test-case appended below,
demo.cu
#include "cuda_runtime.h"

#include "cuda.h"
#include
struct S1 {
long shoud_not_change;

{
long *l_302 = &ptr_arg->irrelevant;
(*l_302) = 0;
return *p_221;
}
__device__ void func_2(struct S1 * ptr_arg)
{
int *l_231 = (int*)0;
func_3(&l_231, ptr_arg);
}

{
func_2(ptr_arg);
}
extern "C" __global__ void entry(long *result)
{
struct S1 c_783 = {
11L, // shoud_not_change
0L, // irrelevant
};
result[0] = (long)c_783.shoud_not_change;
struct S1* ptr_arg = &c_783;
__syncthreads();
func_1(ptr_arg);
__syncthreads();
result[1] = (long)ptr_arg->shoud_not_change;
}
int main(void)
{
long h_result[2];
long* result;
size_t result_size = sizeof(long)*2;
cudaMalloc((void**)&result,result_size);
entry<<<100,100>>>(result);
cudaMemcpy(&h_result,result,result_size,cudaMemcpyDeviceToHost);
printf("result[0] is %ld, result[1] is %ld\n", h_result[0], h_result[1]);

propagated to other branches
Product: new-bugs
Version: trunk

Clang is unable to optimize the next code:
#include
const double& safe_deref(double* a) {
if (a==nullptr) { // expansion of GSL Ensures macro with
GSL_UNENFORCED_ON_CONTRACT_VIOLATION
__builtin_unreachable();
}
if (a==nullptr) {
throw std::runtime_error("error");
}
return *a;
}
GCC optimize out both "if" statements, see https://godbolt.org/g/4hSgAA
