Richard Henderson 6fa617dabc arm: Add argument space for the hidden struct return pointer 
This should have been failing all along, but it's only
exposed by the complex_int test case.

Richard Henderson a4b785ea69 arm: Rewrite ffi_closure 
Move the push of the argument registers into ffi_closure_SYSV,
reducing the size of the trampoline.

Richard Henderson e7f15f60e8 arm: Rewrite ffi_call 
Use the trick to allocate the stack frame for ffi_call_SYSV
within ffi_call itself.

Richard Henderson a74a3aaddb arm: Rewrite vfp_type_p 
Do not modify the ffi_type.  Rearrange the tests so that we
quickly eliminate structures that cannot match.  Return an
encoded value of element count and base type.

David Schneider 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.

Landon Fuller 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.
 2010-09-19 14:36:45 -07:00
Landon Fuller 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.
