skrll 2b3543128f I was a bit over zealous with my last change so revert the 
locked_return_point change.

Loading the instruction at locked_return_point as a return value didn't
work so well.

Thanks to uwe, cube, and dsl.

uwe 6b8eb49dd6 Use PLT for PIC calls to avoid text relocs in the shared library. 2006-01-06 22:46:14 +00:00
uwe 55ad9313a6 In PIC code call setcontext(2) via PLT to avoid text reloc in the 
shared library.

skrll 73b7bdcee7 A couple of fixes to make libpthread really shared, i.e. not have text re- 
locations:

	- Don't declare pthread__switch_away global
	- Do the PIC dance for pthread__switch_return_point and
	  pthread__locked_switch. Ideally these (and other) symbols would
	  be hidden.

Thanks to uwe@, dyoung@ and elad@ for help.

XXX sh3 is still to be done.
XXX vax does strange things.

uwe ffaa72c2cc Adapt to new PIC macros that are now in <machine/asm.h>. Same binary 
code is generated (still with text relocs, but eliminating them is the
next step).

skrll 32069ca6a3 pt_sleepuc was removed a long time ago. 2004-12-01 14:27:01 +00:00
nathanw 45204d9ceb Punt to setcontext() system call if the PSL_T bit (single-step trap) 
is set, so that the single-step trap happens in the thread's context
and not in the middle of _setcontext_u.

XXX might be able to do something here with iret, too, but it needs
more testing.

nathanw cb111b5e34 When _SOFT_FLOAT is defined, don't save or restore user FP context. 
(note: still needs some mk rules tweaking for MKSOFTFLOAT=yes to pass
-msoft-float to asm builds).

nathanw 94fc83a6be Add ucontext conversion macros for an "extra" register set. 2004-02-11 21:04:10 +00:00
he ea56bcee84 Hide the register number constants behind an _R_ prefix, and also 
rename FPBASE to _FPBASE, so that we avoid polluting the user's
name space when e.g. <sys/ptrace.h> is included.  Previously, the
PC symbol in mips/regnum.h would conflict with the declaration of
the external variable by the same name in termcap.h, as discovered
by the ``okheaders'' regression test.

martin 3e8ef3d56a Fix ucontext conversion macros. From Christian Limpach. 2003-11-11 16:21:05 +00:00
martin d708163f7f All the ucontext <-> {fp}reg macros were slightly simplistic and untested 
before (old gdb support on sparc did not use this).
Pointed out by Christian Limpach.
