Bug ID: 51304
Summary: [Matrix] matrix builtin asserts in 32 bit mode.
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org

Matrix builtins __builtin_matrix_column_major_load and
__builtin_matrix_column_major_store are defined to use size_t as their
parameters.
However, at least in the case of __builtin_matrix_column_major_load, the llvm
intrinsic takes an i64 as its second parameter (and it appears the 3rd
parameter to __builtin_matrix_column_major_store).
HOWEVER, on 32 bit systems (or via -m32), the size of size_t is 32 bits!
Therefore, when we emit the call to the intrinsic, we pass it as a 32 bit
value, which causes a Calling a function with a bad signature assertion.
See reproducer/crash dump below.
I ALSO note that the intrinsics take the rest of their size_t parameters as
'llvm_i32_ty', despite being size_t. So there is likely some level of
consistency that needs to happen here.
bash-4.2$ cat temp.cpp
int main() {
int a;
__builtin_matrix_column_major_load(&a, 5, 6, 7);
}
bash-4.2$ ./bin/clang -cc1 temp.cpp temp.cpp -fenable-matrix -triple
i386-unknown-linux-gnu -emit-llvm -o -
