77f823e31f stop trying to assing vfp regs once we are done with the registers 2013-11-13 14:26:57 +01:00
David Schneider
37067ec503 mark all vfp registers as used when done. 
To avoid assigning registers the would fit, once arguments have been on
the stack, we mark all registers as used once we do not find a free
register for the first time.

83038cf24a Implement FFI_EXEC_TRAMPOLINE_TABLE allocator for iOS/ARM. 
This provides working closure support on iOS/ARM devices where
PROT_WRITE|PROT_EXEC is not permitted. The code passes basic
smoke tests, but requires further review.

9e1196444e Add a hard-coded FFI_EXEC_TRAMPOLINE_TABLE arm implementation. 
This implements support for re-mapping a shared table of executable
trampolines directly in front of a writable configuration page, working
around PROT_WRITE restrictions for sandboxed applications on Apple's
iOS.

This implementation is for testing purposes; a proper allocator is still
necessary, and ARM-specific code needs to be moved out of
src/closures.c.

68ce0c383e Add a shell script that generates the ARM trampoline page. 
This generates a page of 340 trampolines, aligned within one page. The
trampolines use pc-relative addressing to reference config data
(context, jump address) from a page placed directly prior to the
trampoline page. This can be used on systems -- such as iOS -- that do not
support writable, executable memory by remapping the executable page
containing the trampolines directly above a newly allocated writable
config page.

69043d0293 Work-around libffi's FP ABI detection. 
On iOS, we must use the AAPCS floating point return value calling
conventions. libffi's ARM implementation will only use these conventions
if __SOFTFP__ is defined, which is not the case when GCC's
-mfloat-abi defaults to 'softfp' instead of 'soft'. To work around this
we manually define __SOFTFP__ for Apple platforms in the ARM-specific
sysv.S.
