* module/language/tree-il/compile-cps.scm (canonicalize, convert):
Simplify handling of branching primcalls so that `convert' only ever
sees branching primcalls in a test context.
* module/language/tree-il/compile-cps.scm (convert): Fold test of
constants directly to their branches without reifying booleans, to
simplify "and" chains early.
* module/language/cps/compile-bytecode.scm (compile-function): Add
support for heap-object? in test context.
* module/language/cps/primitives.scm (*immediate-predicates*):
(*heap-type-predicates*, *comparisons*): New sets of predicates for
which the VM has branching operations.
(heap-type-predicate?): New predicate.
(*branching-primcall-arities*): Make a hash table.
(branching-primitive?, prim-arity): Adapt
to *branching-primcall-arities* being a hash table.
* module/language/cps/type-fold.scm (heap-object?): Add folder.
* module/language/tree-il/compile-cps.scm (convert): Precede heap type
checks with a heap-object? guard.
* module/language/cps/types.scm (&special-immediate): Model all special
immediates (iflags) under this type bit. This makes type analysis
less precise on these values as we have to use ranges instead of sets
to represent the values, but it frees up bits for other purposes,
allowing us to totally model all types in Guile.
(&eof): New &special-immediate value.
(&other-heap-object): New type bit.
Adapt inferrers.
* module/language/cps/type-fold.scm
(define-special-immediate-predicate-folder): New helper, used for
iflag comparisons.
(local-type-fold): Adapt scalar-value for &special-immediate change.
Delegate branch on $values to a primcall to `false?'.
This will allow heap-object? / inum? predicates to do something useful.
* module/language/cps/types.scm (&fixnum, &bignum): Split &exact-integer
into these types. Keep &exact-integer as a union type.
(type<=?): New helper.
(constant-type): Return &fixnum or &bignum as appropriate.
(define-exact-integer!): New helper, tries to make exact integer
results be &fixnum if they are within range. Adapt users.
(restricted-comparison-ranges, define-binary-result!): Use type<=?
instead of = for &exact-integer.
* module/language/cps/type-fold.scm (logtest, mul, logbit?): Use
type<=?.
* module/language/cps/specialize-numbers.scm (inferred-sigbits):
(specialize-operations): Use type<=?.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(DOT_X_FILES, DOT_DOC_FILES, noinst_HEADERS): Add syntax.c and
syntax.h.
* libguile/evalext.c (scm_self_evaluating_p):

* libguile/tags.h (scm_tc7_syntax):
* module/oop/goops.scm (<syntax>):
* module/system/base/types.scm (%tc7-syntax, cell->object):
* module/system/vm/disassembler.scm (code-annotation): Wire up the new
data type.
* libguile/syntax.c:
* libguile/syntax.h: New files.
* module/ice-9/boot-9.scm: Move new definitions to (system syntax
internal).
* module/system/syntax.scm (print-syntax): New helper.
* module/system/vm/assembler.scm (statically-allocatable?)
(intern-constant, link-data): Arrange to be able to write syntax
objects into images.
* module/language/cps/types.scm (&syntax): New type. Remove
&hash-table; it was never detected, an internal binding, and we need
the bit to avoid going into bignum territory.
* module/language/cps/effects-analysis.scm (expression-effects): Prompts
cause &all-effects. I tried to limit this change to CSE but it was
actually LICM that was borked, so better to be conservative
* test-suite/tests/control.test ("escape-only continuations"): Add
test.
* doc/ref/vm.texi (Inlined Scheme Instructions): Add string-set!.
* libguile/vm-engine.c (string-set!): New opcode.
* module/ice-9/rdelim.scm (read-string): Reimplement in terms of a
geometrically growing list of strings, to reduce total heap usage when
reading big files.
* module/language/cps/compile-bytecode.scm (compile-function): Add
string-set! support.
* module/language/cps/types.scm (string-set!): Update for &u64 index.
* module/language/tree-il/compile-cps.scm (convert): Unbox index to
string-set!.
* module/system/vm/assembler.scm (system): Export string-set!.
This bug was introduced by 35a9059250.
* module/language/cps/specialize-numbers.scm (specialize-operations):
Check that both operands are real as a condition for
specialize-f64-comparison.
* test-suite/tests/numbers.test: Add test.
* module/language/cps/compile-bytecode.scm (compile-function): Check for
fallthrough after $kclause too; possible to need to jump if clause
tails are contified.
* module/language/cps/contification.scm (compute-contification-candidates):
Enable inter-clause contification.
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/slot-allocation.scm ($allocation)
(lookup-nlocals, compute-frame-size, allocate-slots): Adapt to
have one frame size per function, for all clauses.
Fixes <http://bugs.gnu.org/20272>.
* module/ice-9/boot-9.scm (module-generate-unique-id!)
(module-gensym): New procedures.
(module): Add 'next-unique-id' field.
(the-root-module): Inherit 'next-unique-id' value from early stub.
(make-module, make-autoload-interface): Adjust calls to
module-constructor.
* module/ice-9/psyntax.scm (gen-label, new-mark): Generate unique
identifiers from the module name and the per-module unique-id.
(build-lexical-var, generate-temporaries): Use
'module-gensym' instead of 'gensym'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/fix-letrec.scm (fix-letrec!): Use
'module-gensym' instead of 'gensym'.
* module/system/base/syntax.scm (define-record): Likewise.
(transform-record): Likewise.

* module/language/cps/types.scm (define-binary-result!): Arithmetic
where one argument is a flonum may produce a complex.
* test-suite/tests/compiler.test: Add test.
* module/language/cps/specialize-numbers.scm (compute-significant-bits):
Always revisit predecessors after first visit. Avoids situation where
predecessor of an unvisited phi var could default to 0 significant
bits and never be revisited. Fixes (format #f "~2f" 9.9).
* libguile/vm-engine.c (fluid-set!): Fix name of opcode to correspond
with name of Tree-IL primitive. Fixes compilation of fluid-set! to
actually use the fluid-set! opcode.
* doc/ref/vm.texi (Dynamic Environment Instructions): Update.
* module/language/cps/compile-bytecode.scm (compile-function): Add
fluid-set! case.
* module/system/vm/assembler.scm: Update export name for
emit-fluid-set!.
The compiler was producing `((toplevel foo))' instead of `(toplevel foo)'.
Changed to use `call' form with target type and spliced constructor
arguments.
* module/language/ecmascript/compile-tree-il.scm (comp): Replace `@impl'
shorthand with `call' + `@implv' for better control over resulting
tree-il.
* test-suite/tests/ecmascript.test (compiler): Add test for "new Object();"
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* module/language/cps/slot-allocation.scm
(add-prompt-control-flow-edges): Fix to add links from prompt bodies
to handlers, even in cases where the handler can reach the body but
the body can't reach the handler.
* test-suite/tests/compiler.test ("prompt body slot allocation"): Add
test case.
* doc/ref/vm.texi (Inlined Atomic Instructions): New section.
* libguile/vm-engine.c (VM_VALIDATE_ATOMIC_BOX, make-atomic-box)
(atomic-box-ref, atomic-box-set!, atomic-box-swap!)
(atomic-box-compare-and-swap!): New instructions.
* libguile/vm.c: Include atomic and atomics-internal.h.
(vm_error_not_a_atomic_box): New function.
* module/ice-9/atomic.scm: Register primitives with the compiler.
* module/language/cps/compile-bytecode.scm (compile-function): Add
support for atomic ops.
* module/language/cps/effects-analysis.scm: Add comment about why no
effects analysis needed.
* module/language/cps/reify-primitives.scm (primitive-module): Add case
for (ice-9 atomic).
* module/language/tree-il/primitives.scm (*effect-free-primitives*):
(*effect+exception-free-primitives*): Add atomic-box?.
* module/system/vm/assembler.scm: Add new instructions.
* test-suite/tests/atomic.test: Test with compilation and
interpretation.
* module/language/tree-il/primitives.scm
(character-comparison-expander): Expand out char<? and friends to <,
unboxing the char arguments.
* module/language/cps/types.scm:
* module/language/cps/effects-analysis.scm: Remove mention of char<? and
friends as we won't see them any more. Also fixes#24318.
* module/language/cps/specialize-numbers.scm (truncate-u64): New helper,
truncates a SCM value.
(specialize-u64-binop): Add ulogxor case.
(sigbits-union, sigbits-intersect, sigbits-intersect3)
(next-power-of-two, range->sigbits, inferred-sigbits)
(significant-bits-handlers, define-significant-bits-handler):
(significant-bits-handler, compute-significant-bits): Add facility to
compute the bits in a value that are significant.
(specialize-operations): Unbox in more cases, when only u64 bits are
significant. Unbox logxor. Elide logand where it has no effect.
* module/language/cps/rotate-loops.scm (rotate-loops-in-function): Don't
attempt to rotate a loop whose header is a $prompt. Fixes use of
`continue' in `while'. Thanks to Nala Ginrut for the report :)
* doc/ref/vm.texi (Top-Level Environment Instructions): Update
documentation.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, sadly.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* libguile/vm-engine.c (define!): Change to store variable in dst slot.
* module/language/tree-il/compile-cps.scm (convert):
* module/language/cps/compile-bytecode.scm (compile-function): Adapt to
define! change.
* module/language/cps/effects-analysis.scm (current-module): Fix define!
effects. Incidentally here was the bug: in Guile 2.2 you can't have
effects on different object kinds in one instruction, without
reverting to &unknown-memory-kinds.
* test-suite/tests/compiler.test ("regression tests"): Add a test.
* module/language/tree-il/peval.scm (peval): Don't
inline (call-with-values foo (lambda (x) exp)) to (let ((x (foo)))
exp). The idea is that call-with-values sets up an explicit context
in which we are requesting an explicit return arity, and that dropping
extra values when there's not a rest argument is the wrong thing.
Fixes#13966.
* test-suite/tests/peval.test ("partial evaluation"): Update test.
