Landon Fuller 8e7652ef6a Add a libffi-ios-specific github README. 2010-09-19 19:49:39 -07:00
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.

Landon Fuller 19afda0069 Enable AC_SUBST for FFI_EXEC_TRAMPOLINE_TABLE 2010-09-19 14:20:52 -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.

Landon Fuller f38364b399 Fix symbol prefix for ffi_closure_SYSV_inner on Darwin. 2010-09-19 10:42:36 -07:00

Landon Fuller c71480eaf8 Update automake/autoconf to conditionally build src/arm/trampoline.S if FFI_EXEC_TRAMPOLINE_TABLE is enabled. 2010-09-19 09:02:05 -07:00
Landon Fuller 9af9291b73 Add the trampoline table generated by gentramp.sh 2010-09-19 08:52:33 -07:00
Landon Fuller 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.

Landon Fuller 75af086be8 Update autoconf files 2010-09-18 18:12:19 -07:00
Landon Fuller 1ac92cca9b Add autoconf check for W^X platforms that require a trampoline table. 
This adds the FFI_EXEC_TRAMPOLINE_TABLE. The flag is enabled for
arm-apple-darwin, where PROT_EXEC on writable (or formerly writable) pages is
not permitted for sandboxed binaries.

Landon Fuller 8ddac835b6 Fix placement of the __APPLE__ macro. 2010-09-18 15:38:06 -07:00
Landon Fuller 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.
