fvdl 1db3b7489b New files for the changed interrupt code. i8259.c deals with some of 
the old ('legacy') i8259 code, intr.c now contains the bulk of
the interrupt establish/disestablish code.
 2002-11-22 15:05:23 +00:00
fvdl 0caa98d6b8 .s -> .S rename 2002-11-22 15:02:12 +00:00
fvdl c403116289 .s -> .S rename. New files: vector.S and spl.S, they have been split 
off from locore.s, plus parts of isa/vector.s and isa/icu.s
 2002-11-22 15:01:15 +00:00
fvdl 71a8119df8 Renamed to .S 2002-11-22 14:57:32 +00:00
fvdl 518afbd262 Renamed to .S, locore.s was split up too. 2002-11-22 14:55:11 +00:00
fvdl fe506424c6 Removed in the new intr world. 2002-11-22 14:53:05 +00:00
fvdl e2b6067204 Removed, no longer needed. Defines were either dupilcates, or have been 
moved to other files.
 2002-11-22 14:43:32 +00:00
fvdl 45cffa1bd6 These files have been given a proper .S extension, they will come back 
to life as such.
 2002-11-22 14:39:26 +00:00
fvdl e4703e808c The ioapic interrupt code has been folded together with the i8259 
interrupt code.

simonb 7a17e24ac5 Remove pc532-only hacks to access wildly different interrupt accounting 
now that interrupts are tracked with evcnt(9) on this port.
 2002-11-22 13:30:34 +00:00
simonb fe72c084d6 Switch to using evcnt(9) to track interrupt counts. 2002-11-22 13:26:39 +00:00
simonb 11823a584d Only warn on double-word displacements for displacements less 
than -0x20000000, not -0x1f000000.  Quells the endless stream
of
	ld: Double word displacement -535682276, out of range
style warnings that have annoyed my once too often.

wiz e78e668887 Fix typo (responsiness -> responsiveness). 2002-11-22 12:20:58 +00:00
wiz 34fa57de10 Use correct macro. 2002-11-22 12:15:27 +00:00
thorpej 95681d5fa6 Note some recent toolchain changes. 2002-11-22 06:46:45 +00:00
thorpej 6dba3a7439 Split crtbegin/crtend into crti/crtbegin/crtend/crtn. NetBSD-specific 
things like the .note.netbsd.ident section are provided by crti/crtn.
crti/crtn also provide the _init() and _fini() routines.

crtbegin/crtend now only provide support for ctors/dtors.  This paves
the way to using the "crtstuff" provided with GCC (when we upgrade to
GCC 3.3), which provides, among other things, much better C++/Java
exception handling.

junyoung 2cc0cde8f5 Now _rtld_relocate_objects() returns with error as soon as any of 
subsequent calls in it fails.

Spotted by wiz and enami.

manu f528c56f39 Check for excessive recursive Mach-O loading 2002-11-21 22:30:32 +00:00
manu ae6b5562b1 Remove a debug message that has been committed by mistake. 2002-11-21 22:01:45 +00:00
manu af59b63bbd We now have the exact stack initial stack layout of Darwin: 
macho_hdr, argc, *argv, NULL, *envp, NULL, progname, NULL,
*progname, **argv, **envp

Where progname is a pointer to the program name as given in the first
argument to execve(), and macho_hdr a pointer to the Mach-O header at
the beginning of the executable file.

thorpej ecce995e37 Note the ARM ELF "softvfp" object marking change, and the resulting 
(somewhat minor) flag-day.
 2002-11-21 18:05:59 +00:00
thorpej 9022b5f984 In ASM_SPEC: 
* If -mhard-float is passed to the compiler, pass -mfpa10 to the assembler.
* If -msoft-float is passed to the compiler, pass -mfpu=softvfp to the
  assembler.
* If neither -mhard-float nor -msoft-float are passed to the compiler,
  pass -mfpu=softvfp to the assembler.

These changes properly mark objects as using soft-VFP, as is the default
code generation for NetBSD ARM ELF.

oster 9768cda12b Fix up locking on a call to rf_update_component_labels(). 
Noticed by Manuel.  Thanks Manuel!

jdolecek 2ca4879bd1 g/c also mips-specific linux ELF copyargs function prototype and 
linux ELF defines, use generic Aux32Info instead
this also adresses kern/19047 by FUKAUMI Naoki
 2002-11-21 15:32:32 +00:00
jdolecek 0a624a0c15 back previous off; port can only supply LINUX_ELF_AUX_ENTRIES if it also 
overrides the ELF copyargs function

wiz 718523a184 gcc-3.2.1 out, and sort pdisk entry. 2002-11-21 12:38:36 +00:00
thorpej aedbc29a82 Various changes to support soft-vfp: 
* FPU_MEMMULTI -- only include the FPU_FPA10 bit.
* FPU_ARCH_VFP -- define, meaning "uses VFP-format layout".
* FPU_FPA -- define short-hand for (FPU_CORE|FPU_FPA10).
* FPU_DEFAULT -- FPU_ALL -> FPU_FPA.
* Floating point instructions -- FPU_ALL -> FPU_FPA.
* Also set F_SOFT_FLOAT if FPU_ARCH_VFP.
* Set F_VFP_FLOAT if FPU_ARCH_VFP.
* md_atof: lay out bytes properly if using VFP.
* Accept -mfpu=softvfp.
* For -mall, set the FPU part of cpu_variant to FPU_FPA, instead of
  FPU_ALL.

thorpej fafe44f640 From bintuils-current: 
In elf32_arm_merge_private_bfd_data(), if the input-bfd and output-bfd
do not have matching VFP indication, report an error.
 2002-11-21 06:27:33 +00:00
thorpej efce487d2d Define the header bit indicating VFP-format floating point. 2002-11-21 06:25:57 +00:00
thorpej 89780fb9d3 Remove, with extreme prejudice. 2002-11-21 02:13:44 +00:00
chris a7be705a3c Take the newly added kern.ldscript for handling ELF->a.out from jason, and 
apply to the cats kernel build. Seems to work happily for me.

simonb ecf6315bd0 Include <machine/intr.h> to get "struct iv" (in pc532-specific code). 2002-11-21 01:39:15 +00:00
thorpej 75ea1c1fd8 Use a linker script to craft and ELF image that will work 
when copied to a.out via objcopy.  Stop using that frightening
elf2aout.sh shell script.
 2002-11-21 01:38:41 +00:00
simonb 4c350ad4fa Put back extern declaration of scn_cd so this builds again. 2002-11-21 00:23:24 +00:00
simonb 1591afc22d Include <sys/conf.h> to get the dev_type_* macros. 2002-11-21 00:22:10 +00:00
manu 1af0fa979f Better immitate Darwin startup stack layout: there is a slot for the program 
name after envp, and the 0x1000 at the beginning is a pointer to the binary
mach header (we don't emulate this correctly yet).

itojun b39cb313c6 verify strvis() buffer length is enough. make sure string termination before 
use.  remove extra ntohs() which is not needed.  from Charles Blundell

bouyer 59fc067cf7 For sis_setup_channel, acer_setup_channel, hpt_setup_channel, 
pdc202xx_setup_channel, pdc20268_setup_channel:
Properly compute the address of the DMA control register for channel 1.
I think the controllers ignore these bits, I suspect it's only there so that
the BIOS can tell the OS is has configured DMA, but better be correct.
Thanks to Alexander Yurchenko for pointing this out.
