ryo 843ce00650 In some arch, _mcount() would be called recursively when built with COPTS=-O0. 
Normally, functions called from mcount.c are expected to be expanded inline,
so _mcount() will never be called recursively. But when build with COPTS=-O0,
`static inline' functions aren't inlined, and _mcount() will be called
recursively.

Even if _mcount() has `__attribute__((__no_ instrument_function__))',
it has no effect on the calling external (no-inlined) function.

To avoid this, PROF.<fn> is added can be set the profiling flag of any file.
"PROF.mcount.c" is set to blank by default, mcount.c itself is compiled
without -pg.

README.md

NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.

Building

You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:

./build.sh -U -u -j4 -m amd64 -O ~/obj release

Additional build information available in the BUILDING file.

Binaries

Testing

On a running NetBSD system:

cd /usr/tests; atf-run | atf-report

Troubleshooting

Latest sources

To fetch the main CVS repository:

cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P src

To work in the Git mirror, which is updated every few hours from CVS:

git clone https://github.com/NetBSD/src.git
