New features and enhancements:
- The compiler option form "--sysroot arg" is now handled like the
documented "--sysroot=arg" form.
- Added support for caching ".su" files generated by GCC flag
"-fstack-usage".
- ccache should now work with distcc's "pump" wrapper.
- The optional unifier is no longer disabled when the direct mode is
enabled.
- Added support for nvcc compiler options "--compiler-bindir/-ccbin",
"--output-directory/-odir" and "--libdevice-directory/-ldir".
- Boolean environment variable settings no longer accept the following
(case-insensitive) values: "0", "false", "disable" and "no". All other
values are accepted and taken to mean "true". This is to stop users
from setting e.g. "CCACHE_DISABLE=0" and then expect the cache to be
used.
- Improved support for "run_second_cpp = false": If combined with
passing "-fdirectives-only" (GCC) or "frewrite-includes" (Clang) to
the compiler, diagnostics warnings and similar will be correct.
- An implicit "-MQ" is now passed to the preprocessor only if the object
file extension is non-standard. This should make it easier to use
EDG-based compilers (e.g. GHS) which don't understand "-MQ".
- ccache now treats an unreadable configuration file just like a missing
configuration file.
- Documented more pitfalls with enabling "hard_links"
("CCACHE_HARDLINK").
- Documented caveats related to colored warnings from compilers.
Bug fixes:
- File size and number counters are now updated correctly when files are
overwritten in the cache, e.g. when using "CCACHE_RECACHE".
- "run_second_cpp" is now forced for nvcc.
- Fixed how the nvcc options "-optf" and "-odir" are handled.
