With compatibility for ev6 and non-ev6 builds, as the non-ev6 did
manage to get definitions emitted for the float and double functions.

This patch introduces two new convenience functions to set the default
thread attributes used for creating threads. This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.

The macros in lowlevellock.h are returning positive errors, but the
users of the macros expect negative. This causes e.g. sem_wait to
sometimes return an error with errno set to -EWOULDBLOCK.

Adds new SIGBUS error codes for hardware poison signals, syncing with
the current kernel headers (v3.9). It also adds si_trapno field for
alpha.

These macros often set up a variable that later macros sometimes do
not use. Add unused attribute to avoid that.
Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning. Replace this with a dummy reference.

Function pointers on ia64 are like parisc -- they're plabels. While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.
Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.

The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer. The signness doesn't matter here, so
convert it to unsigned.

The recent change to clean up these defines missed the ia64 logic.
Update it accordingly.

For arm this makes no difference--the result is bit-for-bit identical;
for thumb this results in smaller encodings. Perhaps it ought not and
this is in fact an assembler bug, but I also think it's clearer.

Factor out the sequence needed to call kuser_get_tls, as we can't
play subtract into pc games in thumb mode. Prepare for hard-tp,
pulling the save of LR into the macro.

There are several places in which we access negative offsets from
the thread-pointer, but thumb2 only supports positive offsets in
memory references.
Avoid duplicating the rather large macros in which these references
are embedded by abstracting out the operation.
|
|
|
|
|
| |
Macro-ising the few instances where we need to distinguish between
arm and thumb pc-relative memory operations.

Some routines are written with complex LDM/STM insns that cannot be
used in thumb mode, or are highly conditional requiring excessive
IT insns.
When a future patch goes in to enable thumb2 by default, this marker
will be used to override that default.

These are ignored by the assembler in ARM mode, so by
default this has no effect on generated code.
|
|
|
|
|
| |
Scour the source for raw "-8" adjustments that are related to the
offset created by reading the pc.

When compiling with -mthumb, ld.so itself also needs __libc_do_syscall.

Recent changes in malloc-sysdep.h exposed this error, the
symptom being __set_errno was not defined early enough.
