AAPCS (EABI) requires that VFP D8-D15 are always saved, regardless whether
...
the soft float or hard float ABI is being used. However, if there isn't a
FPU that can't be done. So only save/restore them if a FPU is present. When
libc initializes, it does a sysctl to determine if there is a FPU and stores
the result which _setjmp/setjmp uses. If there was a FPU, the magic in the
jmp_buf is changed to reflect that the VFP registers were saved. longjmp uses
the magic to determine if it needs to restore the VFP registers.

Fix the build, _UC_UNIQUE has been renamed _UC_TLSBASE
2012-09-12 14:13:43 +00:00
bba80928a8
setcontext() used to be incompatible with -lpthread since it affected
...
the TLS pointer, therefore wrecking the pthread environement.
Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)
that controlled whether setcontext() would change the TLS pointer.
This change let libpthread override setcontext() with its own version
that unsets _UC_TLSBASE, enabling safe usage of setcontext() with
-lpthread.
We also have the following required changes here:
- rename alpha's _UC_UNIQUE into _UC_TLSBASE
- add _UC_TLSBASE definition in header file for all ports
(powerpc, sh3, sparc and sparc64 lack the implementation for now)
- introduce a libc stub that can be overriden for setcontext()
- modify MD libcs swapcontext() implementations so that they use the
setcontext() libc stub instead of doing a plain system call.
While we are there:
- document various MD _UC_* flags in header file
- add libc and libpthread tests for swapcontext() behavior
(hopefully helpful to spot MD problems introduced with this change)
Future work:
- Deciding whether kernel support or _UC_TLSBASE should be added for
powerpc, sh3, sparc and sparc64 is left to portmasters
