* Add a new predefined preprocessor symbol "__FreeBSD_cc_version",jdp1998-10-292-2/+2
| | | | | | | | | | | | | | | | | | | | | | with a numeric value that describes the feature level of the compiler. This can be used to check for the presence/absence of FreeBSD-specific compiler features. The value is a decimal number whose digits have the form VRRRRFF, where: V = Compiler vendor. 0 (elided) means gcc. RRRR = Vendor's version number, e.g., 2721 for the current gcc version (2.7.2.1). FF = FreeBSD-specific revision level. 00 means the stock compiler from the vendor. The value of "__FreeBSD_cc_version" is hard-coded in "src/contrib/gcc/config/i386/freebsd.h" and must be incremented when new FreeBSD-specific compiler features are added. I considered simply picking up the value of FreeBSD_version from <osreldate.h>. But that would break cross compiles of gcc. PR: Part of the fix for gnu/8452 Suggested by: bde

It's cleaner than it was before, but it's still pretty crufty. Don't cheat on your make world for this update. A lot of things have to be rebuilt for it to work, including the compiler and all of the profiled libraries.

* Support printf format checking of FreeBSD kernel formats %[Dbrz].bde1998-08-243-2/+69
| | | | | | | | | | | | This is enabled by the undocumented option -fformat-extensions. This option should be named better and/or give more control over the extensions. Fixed a message - don't warn about the field width when it's the precision that has the wrong type. Didn't fix excessive checking for the precision relative to the type - ANSI requires both to be ints, but gcc permits the field width to be either int or unsigned int.

See the node "Function Attributes" in the GCC info pages if you don't know what this is all about. This change will allow us to add format string checking for the err(3) family of functions.

* On i386, freebsd.h and freebsd-elf.h have been merged to combinejb1998-03-131-71/+0
| | | | | | | | aout and elf support. freebsd-elf.h died as a result, so the BINFORMAT test for elf in src/gnu/usr.bin/cc/cc_tool/Makefile will need to use freebsd.h, not freebsd-elf.h. That means that alpha will have to go the same way. The new alpha/freebsd.h has the alpha/freebsd-elf.h definitions merged in.
* Nuke crti.o from the STARTFILE_SPEC again. No asm code is needed on alpha.jb1998-03-111-1/+8

* Change the LINK_SPEC to specify the same runtime loader as used onjb1998-03-101-12/+6
| | | | | | | | | | | | | | | | | | | i386-elf because that is what will be used for FreeBSD/Alpha. Change the STARTFILE_SPEC to match the non-aout version of i386 so that the csu files can be built in exactly the same way as i386-elf. This means that FreeBSD/Alpha departs from NetBSD/Alpha which uses crt0 and crtbegin/crtend. Since i386-aout uses crt0, I guess it was decided that i386-elf should use crt1. i386-elf also references crti and with this change, so does FreeBAS/Alpha. I think it is important for FreeBSD to have a consistent implementation across architectures and since ELF is quite compatible (ignoring differences in 32 and 64 bits), gcc might as well be configured the same. Another change is that the entry symbol is _start, not __start as in NetBSD.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a.out gas and the binutils gas (elf or a.out) with a single compiler. This uses other infrastructure not yet committed, in order to support both a.out and elf it needs to be able to get to both a.out and elf gas, ld, libs, crt* etc. So for now, the support is pretty much dormant. The new freebsd.h file is based on the old freebsd-elf.h file (which has a long lineage, right back through linux and svr4 files). The change is pretty dramatic from a gcc internals standpoint as it overrides a lot of definitions in order to generate different output based on target mode. There is potential for screw-ups, so please be on the lookout - gcc's configuration mechanism wasn't really meant for this kind of thing. It's believed to compile world etc just fine under both a.out and elf, can handle global constructors and destructors, handles the differences in a.out and elf stabs, and what sections things like exceptions go in. The initial idea came from i386/osfrose.h which is a dual rose/elf format target. These two are not as diverse as a.out and elf it would seem. The cc front-end uses external configuration to determine default object format (still being thrashed out, so read the source if you want to see it so far), and has a '-aout' and '-elf' override command line switch. There are some other internal switches that can be accessed, namely -maout, -mno-aout, -munderscores and -mnounderscores. The underscore and local symbol prefixing rules are controllable seperately to the output format. (ie: it's possible to generate a.out without the _ prefixes on symbols and also to generate elf with the _ prefixes. This isn't quite optimal, but does seem to work pretty well, except the linkers don't always recognise the local symbols without their normal names) The default format is a.out (still), nobody should see any major changes.

| | | | | | | | | | | | | | | See freebsd.h and freebsd-elf.h for the silly comment that cgd@netbsd.org wanted me to add about his claim that uncommented source files that have been publicly available for ftp for nearly a year; that are configuration patches to a GPL'ed program; are owned by his previous employer who refuses to release them. Well... I did as he said. As if that makes a difference! At this point we've got cpp, gcc, g++ ported to FreeBSD/Alpha so all the code that uses __FreeBSD__ is correctly pre-processed. Yay. I'll commit the bootstrap makefile next to let others play, then on to libc.
