| | | | | | | | | | | | | | understand that non-local variables can never be collected, and when it collected the static variable for mexitcount_libfunc, gcc aborted on the next use of this variable. This quick fix is to reinitialize the variable on every use and depend on garbage collection recovering the small amount of memory wasted by this, and not worry by the small amount of time wasted by this. It would be better to initialize the variable together with most of the other libfuncs in optabs.c and depend on whatever magic is there to prevent its collection, but we initialize it here to avoid taking at least 2 more files off the vendor branch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of thepeter1996-09-181-0/+5703
non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.
