The support for unnamed struct/union members that was added in decl.c
1.60 from 2015-10-13 was simple but wrong. It didn't cover initializers
of these structures and computed wrong sizes for structures containing
anonymous unions. At that time, the handling of initializers was broken
as well, it was fixed 6 years later in init.c 1.229 from 2021-12-22.
Real-life examples for code that lint couldn't handle are:
* external/bsd/jemalloc/dist/src/jemalloc.c
* external/mit/xorg/lib/dri.old/Makefile
When bit-fields in packed structs were added on 2009-10-02, lint assumed
that they would only use 'signed int' or 'unsigned int' as storage unit,
even though C99 also allows _Bool.
The cleanup commit for decl.c 1.225 from 2021-08-28 accidentally changed
the rounding mode for bit-field storage units from round-up to
round-down.
Restore part of local modifications r. 1.2 & 1.4 from tsarna@. One
aspect could not be carried forward, as Apple dropped the bug detection
query functionality that was formerly represented by the teststate
member of the DNSServer struct. Otherwise, reapplied almost verbatim,
except for minor consistency and style changes.
This was added again in part as an example should there be a need to
add further logging content for NetBSD's purposes. (DumpStateLog() has
changed further as of Apple's 1790.80.10 release, but should we roll
forward, our means here should still be viable.)
Add details about the header structure (though the if_npflog.h file is
not presently installed and has a _KERNEL guard). Also adjust some
sentences (requested by riastradh@), and include the original OpenBSD
RCS ID, since much of this content shares that origin.
Previously, primary bootstrap was able to boot on RAID-1 RAIDframe set
with the limitation that the FFS filesystem had to start at bloc 0 in the
RAID. That allowed inner RAID partitionning with a disklabel, but not with
a GPT.
When booting on a RAID-1 RAIDframe, primary bootstrap now first try a
filesystem at bloc 0 of the RAID as before. On failure, it tries to
read a GPT and load secondary bootstrap from, by priority;
1) the first partition with the bootme attribute set
2) the first partition of type FFS, LFS, CCD or CGD
3) the first partition present in the GPT
Only print the debug message if the diagnostic is active, which is
relevant for c99ism, c11ism and gnuism.
Print more details about the diagnostic or query.
When running the tests via ATF, the filename was an absolute filename,
while the preprocessing line in the test file uses a relative filename.
These two didn't match.
- cache DEC and FG registers, only write them if the value actually changes
- wait for the engine to go idle before writing DEC
- wait for FIFO slots on everything else
with this we avoid waiting if possible and still avoid overlapping blit and
fill commands
we get occasional overlap with blit commands if we just wait for fifo slots
needs further investigation, it is possible that not all writes to drawing
engine registers are pipelined and of course we don't have docs
