g77 has likely not shipped as a binary in a long time.
No change for netbsd src as it has no fortran code, no change for pkgsrc
because it passes ${FC} for fortran packages.
Always define -fsanitize=${USE_SANITIZER} and
-fsanitize=${USE_LIBCSANITIZER} before other flags defined with
SANITIZERFLAGS and LIBCSANITIZERFLAGS.
This allows to overwrite rules that are parsed from left to right.
With the current approach it wasn't possible to disable some checks, as
they were reenabled again by the "-fsanitize=" argument.
Add flags that are required to build a program and a dynamically loaded
library.
Propagade LIBCSANITIZERFLAGS to CFLAGS and CXXFLAGS.
LDFLAGS is not changed on purpose, as a libcsanitizer is inside libc
and no external dependencies are needed.
Register NOLIBCSANITIZER, as certain distribution parts will need to be
skipped.
This change:
* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.
* Removes the PMC code of ARM XSCALE.
* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.
* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.
* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.
* Removes the pmc_evid_t and pmc_ctr_t types.
* Removes all the associated man pages. The sets are marked as obsolete.
support for only one ARM CPU. It used to have x86 support, but it was broken
and I removed it. The legacy PMC interface will be removed from the kernel
too. Sent on tech-kern@ yesterday, thorpej was fine.
A new keyword SANITIZER_RENAME_SYMBOL. It's a variable that has specified
a list of symbols to be renamed in a processor in order to remove naming
conflicts with public symbols in libc/m/pthread/rt.
This renaming will occur for libraries and programs.
A symbol with a conflicting 'name', will be renamed to '__mksanitizer_name'.
Based on an idea by <christos>
Note that the list of sanitizer features is just a selection, not a
complete list. Include there LSan and Scudo. Missing: hwmsan, esan,
ubsan_minimal etc.
Explain that USE_SANITIZER is an argument passed to -fsanitize= and it can
contain multiple options.
Mention SANITIZERFLAGS to pass even more sanitizer arguments.
Stop tracking in this file what compiler compiles what features. Just note
that the selection of supported features depends on a compiler version and
target CPU architecture.
Introduce a new variable SANITIZERFLAGS that contains all the sanitizer
specific flags. These flags are designed to be passed to CFLAGS, CXXFLAGS
and LDFLAGS.
Pass SANITIZERFLAGS in bsd.prog.mk rules to CFLAGS, CXXFLAGS and LDFLAGS.
Pass SANITIZERFLAGS in bsd.lib.mk rules to *_pic.a build flags. The *_pic.a
libraries are designed to construct .so libraries. All .so libraries with
few exceptions are expected to be prebuilt with a sanitizer. Another
purpuse of *_pic.a files can be constructing static PIE programs, however
they are not supported as of now and there is no sanitization of static
programs either.
Once MKSTATICPIE will be supported, it will be initially incompatible with
MKSANITIZER.
This change also makes it easier to build other targets like kernel and
kernel modules without userland sanitizers.
No functional change intended for MKSANITIZER=no users.
Allow to disable building groff. This is a build tool written in C++.
This option is useful with an external toolchain configured for building the
distribution rather than building tools (e.g. C++ lookup paths may differ).

use ${LD} ${LDFLAGS} -r which does not work if we specify MKRELRO since
LDFLAGS is supposed to be passed to LINK.c not LD directly (although some
of the flags work).
of /libdata/firmware and /usr/libdata/firmware are not installed
if set to "no". from the bsd.README:
MKFIRMWARE If "no", install the /libdata/firmware directory,
which is necessary for several drivers: athn(4), bwfm(4),
ipw(4), iwi(4), iwm(4), iwn(4), otus(4), rtwn(4), urtwn(4),
wpi(4), ral(4), rum(4), run(4), zyd(4), bcm43xx(4), and
the Tegra 124 SoC.
Default: yes on amd64, cobalt, evbarm evbmips, evbppc, hpcarm,
hppa, i386, mac68k, macppc, sandpoint, and sparc64, no elsewhere.
convert MKRADEONFIRMWARE and MKTEGRAFIRMWARE into FOO.arch lists,
and move their defaults above the general defaults setting.
saves about 12MB in a normal installation for other platforms.
