used for argument passing, plus %rax (used to pass the number of float
arguments to varargs functions), to avoid having it clobber caller-saved
registers. mcount is emitted "under the radar", so the compiler doesn't
know it should do this.
Change the kernel mcount entry/exit macros to use plain cli/sti, like on i386.
wrong on the semantic front; the spurious wakeup confuses Darwin's gdb.
Allow vm, task and thread operations on remote processes. The code to pick up
the remote process is in mach_sys_msg_trap(), so that any Mach service can
use it.
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.
To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.
bus_space_write_4(tag, handle, offset, value)
becomes
bus_space_write_4(tag, handles[offset], 0, value)

and on cmdide (sparc64).
down to a cylinder boundary before adding in the requested size.
Stops the partition being one cylinder larger than requested when the
partition doesn't start at the beginning of a cylinder (eg for partitions
starting in sector 63).
Fixes part of PR install/23548
with the shell's command to change limits. Make the PTHREAD_STACKSIZE
environment variable override the default stack size. The old fixed
stack size behaviour can be enable with PT_FIXEDSTACKSIZE_LG when building
libpthread.
is moving here, keeping everything together.
tested with: vax (old config), mac68k (old config), i386 (new config)
and shark (new config). tested i386 binaries only so far, but the
system seems to be surviving the self-hosted test.
XXX: note that this isn't *all* the bits required to run a binutils
2.14 world for arm or i386; these will come soon enough...
