GNU lightning 2.0.5 released!

GNU lightning is a library to aid in making portable programs
that compile assembly code at run time.


Download release:

2.0.5 comes with a new port to the Alpha architecture. Thanks
to Many Trent Nelson from for providing access to
an Alpha computer.


o Correct assertion on uninitialized state variables.

o Implement lightning Alpha port.

o Correct wrong table of instruction sizes in software float.
o When checking cpu features, do not get confused on Linux if /proc
is not mounted, and end up not properly checking for __ARM_PCS_VFP,
that is the best source to know if a fpu is available.

o Correct usage of wrong register in jit_bmsr, that was working
(passing all tests) by accident.

o Add consistency check on temporaries during a jump.
o Always mark return registers as live in epilog.
o Correct change of possibly wrong bitmask in jit_update.
o Convert all assertions to result in an int check.
On alpha assertions directly on a pointer or long would fail if
only checking the top 32 bits.
o Do not pass null as free, memcpy and memmove arguments.
o Remove the global but not advertised jit_progname variable.
o Add note about initialization and jit_set_memory_functions call.
o Do not export some expected to be private definitions and types in
