Bug ID: 47190
Summary: Provide way to specify threshold for -Wmisexcept
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org
Reporter: david.bolvan...@gmail.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,
richard-l...@metafoo.co.uk
Nowdays, -Wmisexpect warns too much uselessly, eg.:
../lib/decompress/zstd_decompress_block.c:874:17: warning: Potential
performance regression from use of __builtin_expect(): Annotation was correct
on 90.49% (1747623 / 1931364) of profiled executions. [-Wmisexpect]
It would be great to provide way to specify threshold to stop this warning.
For example, with -Wmisexpect=70 we would not warn for case above.
