+
+ * include/lightning/jit_private.h: Add new 'inst' field to
+ jit_compiler_t, if __mips__ is defined. This field is a simple
+ helper for a pending instruction to be emitted, and that can
+ be emitted out of order.
+ * lib/jit_fallback.c: Update for changes in internal mips patching
+ and jumping macros and function calls.
+ * lib/jit_mips-cpu.c: Core of changes to attempt to fill delay
+ slots with instructions that can be emitted out of order.
+ * lib/jit_mips-fpu.c: Update to use delay slot in branches.
+ * lib/jit_mips.c: Update for new delay slot use logic.
+
+2023-02-20 Paulo Andrade <pcpa@gnu.org>
+
+ * check/float.tst: Add conditionals for mips release for expected
+ NaN truncated to an integer.
+ * check/lightning.c: Add extra preprocessor for mips release.
+ * include/lightning/jit_mips.h: Make the NEW_ABI preprocessor
+ defined to zero if using the n32 or n64 abis. This makes it
+ easier to create runtime checks with an always true or false
+ condition.
+ * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c: Implement mips release
+ 6 support.
+ * lib/jit_mips.c: Add more reliable mips release detection code.
+
+2023-02-09 Paulo Andrade <pcpa@gnu.org>
+
+ * check/Makefile.am: Update for new bit.tst test, to check the
+ new clor, clzr, ctor and ctzr instructions.
+ * check/all.tst: Update to verify encoding of new instructions.
+ * check/lightning.c: Update to have the lightning "assembler"
+ understanding the new instructions.
+ * include/lightning.h.in: Define new codes for new instructions.
+ * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
+ lib/jit_ia64.c, lib/jit_loongarch.c, lib/jit_mips.c, lib/jit_ppc.c,
+ lib/jit_riscv.c, lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
+ Implement fallback version of new instructions.
+ * lib/jit_fallback.c: Actual implementation of the fallbacks of
+ the new instructions.
+ * lib/jit_names.c: Update to print debug information of new
+ instructions.
+
+2023-01-26 Paulo Andrade <pcpa@gnu.org>
+
+ * check/riprel.c, check/riprel.ok: New check files.
+ * check/Makefile.am: Support for new riprel test.
+ * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86.c: Implement
+ %rip relative addressing when reliable. Currently disabled for
+ x32 and _WIN32; could be added for positive relative addresses
+ only where it should work.
+ * lib/lightning.c: Correct problem added in previous patch due
+ to not testing on a 32 bit environment.
+
+2023-01-23 Paulo Andrade <pcpa@gnu.org>
+
+ * lib/jit_mips-cpu.c, lib/jit_mips-cpu.c: Use pseudo instructions
+ "b" (BEQ(0,0,disp)) and "bal" (BGEZAL(0,disp)) for mips2, when an
+ unconditional branch or function call is known to be in range of a
+ relative jump. This should significantly reduce jit size generation.
+
+2023-01-20 Paulo Andrade <pcpa@gnu.org>
+
+ * lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_rewind.c: Adapt
+ code to implement a variable framesize and optimize frame pointer
+ for simple leaf functions.
+
+2023-01-19 Paulo Andrade <pcpa@gnu.org>
+
+ * lib/jit_riscv.c, lib/jit_riscv-cpu.c: Adapt code to use a
+ variable framesize. Previously it was aligning the stack at
+ 8 bytes, not 16. Now functions are called with a 16 byte aligned
+ stack.
+
+2023-01-18 Paulo Andrade <pcpa@gnu.org>
+
+ * include/lightning/jit_private.h: Include new framesize field
+ of jit_compiler_t; add new alist field for jit_function_t; add
+ new cvt_offset and need_stack fields specific to x86.
+ * lib/jit_x86.c, lib/jit_x86-cpu: Rewrite code to create stack
+ frames, so that less stack space can be used if no, or very few
+ callee save registers are modified in a function.
+ * jit_x86-sse.c, jit_x86-x87.c: Make CVT_OFFSET variable, and
+ dynamically allocated; this is required to avoid needing to
+ modify twice %rsp at function prologs, even if no stack space
+ is used.
+
+2022-11-09 Paulo Andrade <pcpa@gnu.org>
+
+ * configure.ac: Add new --enable-devel-strong-type-checking
+ option.
+ * include/lightning.h.in: Rework to not need to know if
+ PACKED_STACK is defined, and add a new argument to _jit_arg,
+ _jit_putarg{r,i}, _jit_pusharg{r,i} and _jit_ret{r,i} to have
+ the same code path if PACKED_STACK is defined or not, and also
+ to implement STRONG_TYPE_CHECK enabled with the new
+ --enable-devel-strong-type-checking.
+ * include/lightning/jit_private.h: Add new macros to add assertions
+ for STRONG_TYPE_CHECK and avoid pasting tokens in jit_inc_synth*
+ when the token is not a static known value.
+ * lib/jit_aarch64.c: The first implementation of the new code,
+ working correctly in Apple M1 and with and without STRONG_TYPE_CHECK
+ in Linux.
+
+2022-11-08 Paulo Andrade <pcpa@gnu.org>
+
+ Add support for packed stack arguments as used by Apple M1
+ aarch64 cpus. This requires a major redesign in how Lightning
+ works, because contrary to all other supported ports, in this
+ case arguments must be truncated and sign/zero extended if
+ passed in registers, but when receiving the argument, there
+ is no need to truncate and sign/zero extend.
+ Return values are also treated this way. The callee must
+ truncate sign/zero extend, not the caller.
+ check/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS.
+ check/all.tst: Implement paired arg/getarg/pusharg/putarg/ret
+ codes to validate they do not generate assertions.
+ * check/allocar.tst, check/call.tst, check/fib.tst, check/put.tst,
+ check/stack.tst: Update to pass in all build types.
+ check/lightning.c: Add new codes for extra codes to handle
+ packed stack.
+ * configure.ac: Add a preprocessor define to know if packed stack
+ need is required. This is not really used, as it was moved to
+ jit_aarch64.h.
+ * doc/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS.
+ * doc/rpn.c: Update to pass in all build types.
+ include/lightning.h.in: Add new codes and reorder enum.
+ * include/lightning/jit_aarch64.h: Detect condition of needing
+ a packed stack.
+ * lib/jit_aarch64-sz.c: Regenerate.
+ * lib/jit_aarch64.c: Major updates for packed stack.
+ * lib/jit_names.c: Updates for debug output.
+ * lib/lightning.c: Update for new codes.
