+2023-04-18 Paulo Andrade <pcpa@gnu.org>
+
+       * include/lightning.h.in: Define new fmar_f, fmai_f, fmsr_f,
+       fmsi_f, fmar_d, fmai_d, fmsr_d and fmsi_d instructions, that

+       to allow having a 'double' immediate in the last argument, for
+       the versions with immediates. The versions with immediates are
+       added for consistency, as they should be very rarely used in
+       common usage of fused multiply add/sub.
+
+2023-04-06 Paulo Andrade <pcpa@gnu.org>
+

+
+       * include/lightning.h.in: Define new unldr, unldi, unldr_x,
+       unldi_x, unstr, unsti, unldr_x and unstr_x instructions.
+       Remove comment about internal backend specific codes, as they
+       are required by unldr_x and unstr_x in some code paths.
+       * lib/lightning.c: Implement generic movi_f_w, movi_d_w and
+       movi_d_ww that are actually the same for all ports.
+       Define generic load/store implementations when unaligned memory

+       * check/lightning.c: Implement calls to the new rich set of
+       instructions, with an immediate argument, mostly which are resolved
+       at code generation time. With the exception of jit_negi_{f,d},
+       jit_absi{f,d} and jit_sqrti_{f,d} that generate code to execute at
+       runtime. This is required because the code generator should create
+       the proper float environment with rounding modes, exceptions, etc.
+       The new jit_depi is just a wrapper to have the second operand as an

+       with immediate operands.

+
+       * lib/jit_fallback.c: Implement fallbacks for new instructions
+       ext, ext_u and dep.

+       of ext, ext_u and dep.

+       * lib/jit_fallback.c: Mips fallbacks now might need a flush of

+       instruction candidate to delay slot.
+       * lib/jit_mips-cpu.c: Flush any pending instruction if it cannot
+       be used in the delay slot. Add calls to fallback clo, clz, cto and

+
+       * 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

+       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.

+       the new instructions.
+       * lib/jit_names.c: Update to print debug information of new
+       instructions.
+
+2023-01-26 Paulo Andrade <pcpa@gnu.org>

+       %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.

+
+       * 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

+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.
+
+2022-10-31  Marc Nieper-Wißkirchen  <marc@nieper-wisskirchen.de>

+       * check/skip.tst: New test.
+       * doc/body.texi: Document the skip instruction.
+       * include/lightning.h.in: Add the skip instruction.
+       * lib/jit_aarch64-sz.c: Update for skip instruction.
+       * lib/jit_aarch64.c: Implement skip instruction.
+       * lib/jit_alpha-sz.c: Update for skip instruction.
+       * lib/jit_alpha.c: Implement skip instruction.
+       * lib/jit_arm-sz.c: Update for skip instruction.
+       * lib/jit_arm.c: Implement skip instruction.
+       * lib/jit_hppa-sz.c: Update for skip instruction.
+       * lib/jit_hppa.c: Implement skip instruction.
+       * lib/jit_ia64-sz.c: Update for skip instruction.

+
+       * check/lightning.c: Remove -Dmacro=value from usage and attempt
+       to parse it. It was buggy and not properly implemented. Now

+       Now it attempts to do as few as possible recomputations when
+       merging state of adjacent blocks, still doing one extra nop pass
+       (in the sense that it will not find any changes) to make sure the
+       logic is correct.
+
+2022-09-30 Paulo Andrade <pcpa@gnu.org>

+       more instructions are required to construct constant and modify
+       movi_p to use a pc relative load from a constant pool.
+       lib/jit_riscv-sz.c: Update for new constant pool code. Most
+       instructions that need 64 bit constants are significantly reduced.

+       * lib/jit_size.c: Update for estimate of code generation size.

+       simple compare and swap atomic operation.
+       * check/lightning.c: Add entries to be able to use
+       the new compare and swap atomic operation. Still missing
+       a general test, only the basic C version.
+       * include/lightning.h.in: Include pthread.h, even if not
+       needing a fallback compare and swap.
