* Use less stack space for temporary storage and C code invocation, aftermiod2004-07-283-30/+24

* Do not overallocate stack space, and keep the stack on a 16-byte boundary.miod2004-07-221-7/+7

| | | | | the old status bits. ok deraadt@
* Use _ENTRY(CERROR) instead of CERROR so correct type info is generated.drahn2004-06-211-2/+2

* In _longjmp(), flush windows rather than attempting to backtrack manually,miod2004-05-042-59/+35
| | | | | | | | | since the latter is not reliable in all cases. This allows ruby to work on sparc64. Problem spotted by claudio@; fix adapted from NetBSD for sparc, FreeBSD for sparc64; ok deraadt@
* It turns out that the so-called fast ffs(3) routines were wrong, as soon asmiod2004-04-012-18/+2
| | | | | | | | | | | | more than one bit is set, as the ff1 instruction counts from the highest order. However, gcc/m88k with optimization enabled would use a correct, short sequence based upon ff1 and tweaks, to achieve the intended result, hence i did not catch this flaw initially. So revert to the C implementation - it is correct, still decently fast, and will only be used when compiling at -O0.
* From the how many ways can you screw up replacing one line of codejason2004-03-241-2/+2
| | | | | department: cast 'i' to u_int64_t so the sign comparison actually makes sense. Any other bugs in here just ship in the release, I'm done.
* use absolute value like rev 1.1 did; pointed out by tom and ok deraadt.jason2004-03-231-1/+2

* gcc3 doesn't align things the same as gcc2. Casting upwards is dangerousjason2004-03-231-2/+3

* longjmp should not return 0, if longjmp(..., 0) is invoked return 1.drahn2004-03-011-2/+8
| | | | ok miod@ deraadt@

* change amd64's MACHINE_ARCH from x86_64 to amd64. There are many manyderaadt2004-02-2742-1879/+2
| | | | | | reasons for this, quite a few of them technical, and not all of them in response to Intel's broken ia32e crud. The gcc toolchain stays at x86_64 for now.
* Define OSYSCALL* macros, as their SYSCALL* counterparts, but using themiod2004-02-224-6/+52
| | | | | | | | | int 0x80 mechanism; and use OSYSCALL for sigreturn() as done in the sigcode. Naming borrowed from NetBSD. ok deraadt@
* errno is int, not long; tracked down by otto@miod2004-02-182-8/+8

* from freebsd, helps awk too:deraadt2004-02-082-4/+4
| | | | | Fix fabs(). This commit brought to you by the letter 'l'. (fstp stores a mem32 value, fstpl stores a mem64 value)
* from freebsd (and appears to make our awk work better)deraadt2004-02-082-34/+28
| | | | | | Tidy up modf.S and make it actually work. It wasn't extracting the value out of ST(0) before copying it to %xmm0. Also remove bogus stack frame and work in the red zone.

|
* ABI breakage happened with the sigaltstack replacement. It is too late,deraadt2004-01-152-8/+8
| | | | | | | now we just have to cope. Since setjmp uses it, the alpha and sparc64 are unhappy with the structure change. In a few days, we will make the second hop here, for now, use the old system call until all binaries have the new struct in them.
* Use correct type for old values. No binary change.otto2004-01-052-4/+4
