* libguile/jit.c: Operands have their ABI in them. We can now have
addends on GPR and MEM operands, which can improve register
allocation. Use new jit_calli_3, etc helper APIs.
* libguile/jit.c (compute_mcode): Move analysis outside the code
emitter, as it doesn't need to re-run on overflow.
(compile): Clear labels before emitting, as they may have changed if we
overflowed.
* libguile/jit.c (fp_scm_operand): Fix assertion about register state.
(compile_call_scm_sz_u32): Fix ABI declaration for immediate.
Some whitespace cleanups as well.
* libguile/jit.c (prepare_jit_state): Remove unused function.
(initialize_thread_jit_state): Since the lightening state is allocated
using GC memory, trace the JIT state.
(compute_mcode): Avoid double-compile.
* libguile/jit.c (struct scm_jit_state): Remove entry_mcode member.
(add_inter_instruction_patch): Fix off-by-one.
(compile): Reset reloc_idx when restarting a compile. All instructions
record their addresses.
* libguile/macros.c (scm_i_make_primitive_macro): Give primitive macros
a primitive-macro macro-type.
* module/ice-9/psyntax.scm (put-global-definition-hook)
(get-global-definition-hook): Inline into uses.
(make-binding): Change format of lexically defined or rebound syntax
parameters to just be the transformer, not a list of the transformer.
(resolve-identifier, expand-install-global, expand-body)
(syntax-parameterize): Adapt to use the variable object (box) holding
the top-level syntax parameter as the "key" for lookups into the
lexical environment, instead of a fresh object associated with the
syntax transformer.
* module/ice-9/psyntax-pp.scm: Regenerate.
Fixes#27476, a horrible race when one thread is expanding a
syntax-parameterize form including uses, and another thread is expanding
the corresponding define-syntax-parameter. See
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27476#102.
* libguile/jit.c (compile_u64_imm_less): Compare high word using
not-equal, to avoid a signedness compare.
(compile_s64_imm_less, compile_imm_s64_less): Fix the not-less cases.
* libguile/jit.c (record_gpr_clobber): If we clobber SP or FP, clear the
appropriate register state bits. Only exercised for 32-bit targets in
practice!
(emit_alloc_frame, emit_push_frame): Fix a couple places where we were
failing to track the register state correctly.
(compile_umul): Remove a needless register state flush, nowthat
qmulr_u has a wrapper that tracks this for us.
* libguile/srfi-14.c (scm_sys_char_set_dump): Silence an erroneous
-Wformat-overflow warning based on an incorrect range inference by
increasing output buffer size.
* doc/ref/compiler.texi (Bytecode): Update macro-assembler instructions,
and move most of them to the instruction set reference.
* doc/ref/vm.texi (A Virtual Machine for Guile, VM Programs): Minor
fixes.
(Instruction Set): Update for Guile 3 instruction set.
* libguile/vm-engine.c (vm_engine): Update a few instruction
docstrings.
* libguile/jit.c (compile_s64_numerically_equal): Remove as this
instruction was removed in previous refactoring.
(compile_atomic_scm_set_immediate), compile_atomic_scm_ref_immediate):
Adapt to change in C name of these instructions.
* libguile/vm-engine.c: Add comments for all instructions.
* libguile/vm-engine.c (abort): If the abort doesn't need to longjmp and
the abort hook was enabled, cache registers first to avoid restoring
a bad IP to the VM.
* libguile/loader.h (SCM_OBJCODE_MINIMUM_MINOR_VERSION):
(SCM_OBJCODE_MINOR_VERSION): Bump version.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* libguile/vm-engine.c: Rearrange opcodes to be contiguous and in a
somewhat sensible order.
