ad a5070151ae - Test+branch is usually cheaper than making an indirect function call, 
so avoid making them.
- When parking an LWP on a condition variable, point the hint argument at
  the mutex's waiters queue. Chances are we will be awoken from that later.

ad da3cc0ffcf Cosmetic and minor debugging changes. 2007-03-05 23:30:17 +00:00
ad de2138164c Remove the PTHREAD_SA option. If M:N threads is reimplemented it's 
better off done with a seperate library.

ad 1ac6a89b79 Conditionalised support for 1:1 threads. Needs associated kernel changes 
and more work to be useful.

he 99f69b6c5f It appears that <sys/lock.h> requires <sys/types.h>, so include that as well. 2004-03-14 12:49:31 +00:00

kleink 9f0429b6cc ; may be a comment character in assembly, use \n as a separator instead. 
This instance spotted by Martin Husemann.

scw 5bd6b99940 Both pthread__lock_ras_start and pthread__lock_ras_end need to be 
explicitly declared global in the asm() statements for the benefit of
SH5 binutils. Otherwise, the assembler/linker (I haven't figured out
which) botches the SHmedia bit when generating GOT references for
these symbols in the shared version of the library.

Ok'd by Nathan.

nathanw 53827081be Adapt to pthread__assert() and remove local debug toggle. 2003-02-15 04:37:04 +00:00
scw 04c6e0b141 pthread__lock_ras_start and pthread__lock_ras_end need to be declared 
as function pointers, not character arrays, for the benefit of
platforms (e.g. SH5) where the two types are quite distinct.
