Sync with OpenBSD This brings: - check for integer overflows in custom allocs - fix potential integer overflows in memory allocation - annotate regexp error messages with source string - better error handling in mkstemp/unlink/fdopen logic 2014-07-27 22:54:13 +00:00			`# $OpenBSD: Makefile,v 1.13 2014/05/12 19:11:19 espie Exp $`

Bring OpenBSD m4(1) off of the OPENBSD vendor branch, and add the -s option, $FreeBSD$ identifiers, and fix initialisation to stderr to happen in a function as stderr is not the same in CURRENT as in OpenBSD. Reviewed by: obrien 2002-04-19 17:26:21 +00:00			`# -DEXTENDED`

Use src.opts.mk in preference to bsd.own.mk except where we need stuff from the latter. 2014-05-06 04:22:01 +00:00			`.include <src.opts.mk>`
Migrate most of tools/regression/usr.bin/ to the new tests layout. I'm starting with the easy cases. The leftovers need to be looked at a bit more closely. Note that this change _does_ modify the code of the old tests. This is required in order to allow the code to locate the data files in the source directory instead of the current directory, because Kyua automatically changes the latter to a temporary directory. Also note that at least one test is known to be broken here. Actually, the test is not really broken: it's marked as a TODO but unfortunately Kyua's TAP parser currently does not understand that. Will have to be fixed separately. 2014-03-16 08:04:06 +00:00

Add the Clang specific -Wmissing-variable-declarations to WARNS=6. This compiler flag enforces that that people either mark variables static or use an external declarations for the variable, similar to how -Wmissing-prototypes works for functions. Due to the fact that Yacc/Lex generate code that cannot trivially be changed to not warn because of this (lots of yy* variables), add a NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this specific compiler warning.

Bring OpenBSD m4(1) off of the OPENBSD vendor branch, and add the -s option, $FreeBSD$ identifiers, and fix initialisation to stderr to happen in a function as stderr is not the same in CURRENT as in OpenBSD. Reviewed by: obrien 2002-04-19 17:26:21 +00:00
Add necessary Makefile.inc1 infrastructure for building on non-FreeBSD The most awkward bit in this patch is the bootstrapping of m4: We can't simply use the host version of m4 since that is not compatible with the flags passed by lex (at least on macOS, possibly also on Linux). Therefore we need to bootstrap m4, but lex needs m4 to build and m4 also depends on lex (which needs m4 to generate any files). To work around this cyclic dependency we can build a bootstrap version of m4 (with pre-generated files) then use that to build the real m4. This patch also changes the xz/unxz/dd tools to always use the host version since the version in the source tree cannot easily be bootstrapped on macOS or Linux.

Only set WARNS if not defined This would allow interested parties to do experimental runs with an environment set appropriately to raise all the warnings throughout the build; e.g. env WARNS=6 NO_WERROR=yes buildworld.

Lower warnings again to 3 the right thing would be to fix the warnings which will be done by discussing with upstream I want the m4 code to stay as close as possible to upstream. 2014-08-07 09:38:27 +00:00
