2.1.4 main features are the new Loongarch port, currently supporting
only Linux 64 bit, and a new rewrite of the register live and
unknown state logic. Now it should be faster to generate code.
The matrix of built and tested environments is:
aarch64 Linux
alpha Linux (QEMU)
armv7l Linux (QEMU)
armv7hl Linux (QEMU)
hppa Linux (32 bit, QEMU)
i686 Linux, FreeBSD, NetBSD, OpenBSD and Cygwin/MingW
ia64 Linux
mips Linux
powerpc32 AIX
powerpc64 AIX
powerpc64le Linux
riscv Linux
s390 Linux
s390x Linux
sparc Linux
sparc64 Linux
x32 Linux
x86_64 Linux and Cygwin/MingW
Highlights are:
- Faster jit generation.
- New loongarch port.
- New skip instruction and rework of the align instruction.
- New bswapr_us, bswapr_ui, bswapr_ul byte swap instructions.
- New movzr and movnr conditional move instructions.
- New casr and casi atomic compare and swap instructions.
- Use short unconditional jumps and calls to forward, not yet defined labels.
- And several bug fixes and optimizations.
