Bug ID: 20389
Summary: clang's error message for inline-asm constraint "=f"
should be more user-friendly
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
clang issues the following error message upon encountering constraint "=f":
error: invalid output constraint '=f' in asm
Rather than simply saying the constraint is invalid, it would be better to
print a message that informs the user how the error can be corrected. For
example, gcc prints the following message:
error: output constraint 0 must specify a single register
