Bug ID: 30930
Summary: Assertion failed: isValidGCCRegisterName(Name) &&
"Invalid register passed in", file
E:\llvm\tools\clang\lib\Basic\Targe tInfo.cpp, line
415
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org

This was revealed by
https://github.com/reactos/reactos/blob/master/reactos/ntoskrnl/ke/i386/cpu.c
and then reduced to:
void foo(void)
{
__asm mov cr2, eax;
}
cl /c compiles it without errors, but clang-cl /c emits:
