Define string max-insn and use it in all tables for the width of the
first column (nroff has variables, shocking, I know). Define only the
width of the first column, the last column gets all the remaining width.
This is mostly non-controversial changes to the cargo-culted markup.
While here - add missing .It to BIOCLOCK so that it's not buried in
the text for the previous item and comment out a paragraph about an
ancient SunOS bug.
in bsd.lib.mk there's a check for "MKDEBUG != no" that will add
-g to CFLAGS (maybe) and to CSHLIBFLAGS (always), given that it
isn't in CFLAGS already.. except the conditional is "||" instead
of "&&" and since the MKDEBUG/NODEBUG checks pass, the CFLAGS
check isn't even performed.
additionally, check CXXFLAGS as well as CFLAGS.
this fixes the attempt to use "-g1" in the llvmrt build, which
fails because the compile lines end up being "... -g1 .. -g ..",
(the "-g" comes from the CSHLIBFLAGS variable in that case.)
this reduces the size of llvm-enabled gallium debug by ~1.5GiB
on amd64.
Previously, passing '-nostdinc -isystem $dir' only searched the given
directory but not any compiler-specific directories.
Discovered by fontconfig, which includes <stdatomic.h> from C11, which
lives in /usr/include/gcc-10 instead of /usr/include.
Change the preprocessor options to '--sysroot' instead, to align them
with how the compiler is invoked using build.sh.
The variables MACHINE and MACHINE_ARCH are guaranteed to be defined,
therefore they don't need to be wrapped in '!empty(...)'.
This is simpler to read and, in case of typos, is more likely to lead to
an error message from make, as a line starting with '!' is interpreted
as a dependency line, while a line using only '==' but not '!=' leads to
a syntax error of the form 'Invalid line type'.
issue with +2M size in every binary by setting max-page-size. This
is the simplest fix; fixing this properly requires a lot more
surgery, and upstream seems uncertain how to fix it properly.
