NEWS FROM VERSION 1.2 TO 1.3
|
|
|
|
o Initial support for x86-64 back-end (mostly untested).
|
|
|
|
o lightning is more strict on casts from integer to pointer.
|
|
Be sure to use the _p variants when your immediates are
|
|
of pointer type. This was done to ease 64-bit cleanliness
|
|
tests.
|
|
|
|
o Many bug fixes.
|
|
|
|
o JIT_FPRET is used as JIT_RET to move return values.
|
|
jit_retval_[fd] is used to retrieve return values.
|
|
|
|
o jit_pushr/jit_popr are deprecated, you need to #define
|
|
JIT_NEED_PUSH_POP prior to including lightning.h if you
|
|
want to use them.
|
|
|
|
o Support for stack-allocated variables. Because of this,
|
|
backends defining JIT_FP should now rename it to JIT_AP.
|
|
JIT_FP is now a user-visible register used in ldxi/ldxr
|
|
to access stack-allocated variables.
|
|

o jit_prepare and jit_retval are now jit_prepare_i and
|
|
jit_retval_i.

|
|
|
o Merge changes from Debian
|
|
|
|
This version was released to have a distributable version of lightning

|
after the recent crack of the GNU FTP machines. It does not fix
|
|
outstanding bugs; I apologize for the inconvenience.
