Bug ID: 30552
Summary: [codeview] LLVM should emit T_CHAR instead of T_INT1
for PDB
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org
Reporter: michaelwoeris...@posteo.net
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The T_INTx and T_UINTx types seem to not be very well supported by the MSVC
debugger, and MSVC itself emits T_CHAR and T_UCHAR for int8_t and uint8_t. We
ran across this problem in the Rust compiler:
https://github.com/rust-lang/rust/issues/36646#issuecomment-250148666
The report there contains many useful details for reference.
The relevant code in LLVM can be found here:
https://github.com/llvm-mirror/llvm/blob/864e0ffb0eb47f848aca60d1f08fc2962fbb5009/lib/CodeGen/AsmPrinter/CodeViewDebug.cpp#L1223-L1240
