This is not wrong, but was unexpected. Using <empty>:H results in '.' which
then using the rest of the conversion was added in RELDIR. This was also
causing an empty _DP_DIRDEPS to resolve to SRCTOP for DIRDEPS.

This logic is potentially included multiple times, so overwrite the temporary

system call information such as system call arguments. Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.
This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it. One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events. This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events. Instead, this function only generates a string
description for known malloc() and RTLD records.

In I/OAT, this is done through the INTRDELAY register. On supported
platforms, this register can coalesce interrupts in a set period to
avoid excessive interrupt load for small descriptor workflows. The
period is configurable anywhere from 1 microsecond to 16.38
milliseconds, in microsecond granularity.

These use ld(1), effectively -nostdlib, and don't need any of these
normal dependencies.
kmod builds also define PROG so just checking for KMOD here seems to be
the easiest to handle it.

RISC-V is a new ISA designed to support computer research and education, and
is now become a standard open architecture for industry implementations.
This is a minimal set of changes required to run 'make kernel-toolchain'
using external (GNU) toolchain.

The hardware supports descriptors with two non-contiguous pages. This
allows issuing one descriptor for an 8k copy from/to non-contiguous but

- Don't bother looking up REVISION/BRANCH/etc from release/, or the
CPUTYPE check, as these are not used for makeman and wastes time. The also

These helper functions can be used to read in or write a buffer from or to
an arbitrary process' address space. Without them, this can only be done
using proc_rwmem(), which requires the caller to fill out a uio. This is
onerous and results in code duplication; the new functions provide a simpler
interface which is sufficient for most existing callers of proc_rwmem().
This change also adds a manual page for proc_rwmem() and the new functions.

Debug data files are now built by default with 'make buildworld' and
installed with 'make installworld'. This facilitates debugging but
requires more disk space both during the build and for the installed
world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
in src.conf(5).

This will save time generating dependency files that we didn't expect
due to cases where SRCS!=OBJS or for building custom targetted objects
in Makefiles that do not end up in the DEPENDOBJS list.
This uses a bmake trick to modify CFLAGS based on ${.TARGET}. A
.PARSEDIR check is done for the sake of MFC safety.

Rather than try to guess at all of the OBJS variables just use SRCS
using the same patterns that mkdep does. This also fixes a mistake
where dependencies were being generated with FAST_DEPEND when they were
not for mkdep. This happens when OBJS!=SRCS as is the case in
gnu/lib/csu where SRCS has 1 file and OBJS has several other files that
does not even contain the 1 SRCS file. Generally in these cases the
OBJS have custom dependencies defined in their Makefile. If we generate
dependencies for those and then load a .depend file, then .IMPSRC may
contain duplicate sources and lead to errors such as:
cc: error: cannot specify -o when generating multiple output files

It was allowed before, but make it very explicit it is allowed now. And
prefer 'bool' to older types that were used for the same purpose -- int and
boolean_t.
Like with the C99 fixed-width types, use common sense when changing old
code.
No igor regressions.

My changes in r291635 broke 'make install*' for DIRDEPS_BUILD but also
revealed that some other targets were not guaranteed to be created if
there was a SUBDIR defined. One example is 'installfiles' was never
defined if SUBDIR was not empty.

The problem was that 'afterinstall' was not coming after SUBDIRs were
installed which was the expectation at least in sys/modules for kldxref.
