danw e8559a61eb mark an asm statement volatile so it doesn't get optimized out 1999-07-07 01:53:38 +00:00
pk 0ffda58ae9 A new implementation of _setjmp/_longjmp that uses the T_FLUSHWIN trap.
This means the stack frame and program counter can restored directly
from the jmp_buf, eliminating the need to backtrack through frames
which does not work in all cases.

tron d7678457d6 Fix definition of infinity. Patch supplied by Richard Earnshaw in
PR lib/7829.

matthias 71dd06e171 Go for correctness instead of speed as suggested by Ian Dall. This fixes
pr#port-pc532/7710.

matthias bb36354c10 Fix spurious page faults by double word aligning the source and not the
destination. Thank's to Ian Dall for this fix.

kleink 15fb0e4315 Shameless hack to reference end if using a.out and _end if using ELF. 1999-06-03 20:14:58 +00:00

kleink c66e4d7122 * Prefix softfloat symbols which require external linkage with _arm32_ to
move them out of user namespace; declare those not requiring external linkage
static.
* In due course, disable those functions that require neither external nor
internal linkage.
Addresses PR port-arm32/7517.

kleink 18d5ba6151 We can shave off a register-register move when using the SVR4 ABI: __errno()
will return its pointer result in a0.

ross c5a82dd848 * New MI man page for fp{set,get}{round,sticky,mask}(3).
* Implement fpgetsticky() for alpha.
* Direct fpsetsticky() and fp{get,set}mask() into alpha kernel via sysarch(2).
* Define new sysarch(2) stub for above and install and distribute sysarch.h
for alpha.  (The fpcr IS user mode r/w, but for reasons beyond the scope
of a commit message kernel calls are needed.) And much kernel Magick is
required before these do anything, but this way programs compiled under
1.4 will DTRT on future snapshots and releases.

While here, move the function to implementation name space.

eeh 713a1d89ff Add _dtoul() which gcc generates a lot. Maybe it should go in another file. 1999-04-04 21:01:39 +00:00
kleink dccf2a15e4 While in transition, conditionally rename _ASM_LABEL(cerror) and
_ASM_LABEL(curbrk) to _C_LABEL(__cerror) and _C_LABEL(__curbrk), respectively,
depending on the object format chosen, to avoid user namespace clashes.

christos e387e174fc Amend for the PLT fixes, things broke last night with the changes to SYS.h
and cerror.S. In particular, the syscalls in the files committed below were
broken.

christos 143dcdbe44 Make cerror an entry and compensate for the PIC_PROLOGUE change in SYS.h 1999-02-07 17:22:25 +00:00
christos cb41675175 Add PIC_PROLOGUE before the PLT call to cerror. ELF dynamic linking needs
this.

jonathan 2d40554ce3 _setjmp.S needs OFFSETOF_SC_{FP,}REGS, so include <machine/signal.h>
even tho _setjmp()/_longjmp() don't manipulate signals.  (more thought?)

matthias f44e783c10 When invoking ALTENTRY, the arguments may not contain spaces (not even
after the ",") or this will fail when cpp is run with -traditional-cpp.

castor 8605fac4eb * Fix typo in Makefile.inc -- byte_swap_2.4 -> byte_swap_4.S
* Change bytes_swap_4.S to have consistent NLEAF and END for swap routine.

bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

kleink 6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

thorpej efd37a7da8 Warn about references to the compatibility vfork() (i.e. the vfork() with
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.

This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.

thorpej e644246e6a Warn about references to the compatibility() sigaction(), sigpending(),
sigprocmask(), sigreturn(), and sigsuspend(), and direct the user to
include <signal.h> to generate the correct reference.
