Bug ID: 65372
Summary: -mprofile-kernel undocumented
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
The -mprofile-kernel option supported by GCC and documented in the output of
GCC --help -v is not documented in the GCC online or info manuals:
$ /build/gcc-trunk-git/gcc/xgcc -B/build/gcc-trunk-git/gcc --help -v 2>&1 |
grep -A1 kernel
-mprofile-kernel Call mcount for profiling before a function
prologue
The lack of more detailed documentation makes it difficult to reason about the
expected behavior in cases such as pr63354.

I filed a feature request to get this implemented in Clang, since the Linux
kernel uses it for the ppc port. The immediate request was for documentation
about the change.
