* module/language/tree-il/analyze.scm (<module-info>): New record type.
(unused-module-analysis): New variable.
(make-unused-module-analysis): New analysis.
(make-analyzer): Add it.
* module/system/base/message.scm (%warning-types): Add 'unused-module'.
* test-suite/tests/tree-il.test (%opts-w-unused-module): New variable.
("warnings")["unused-module"]: New test prefix.
* NEWS: Update.
This reduces the amount of memory that needs to be allocated while
writing the ELF file to disk.
Note: We're abusing #:page-aligned? in 'link-elf' to choose whether to
return a bytevector or a procedure.
* module/system/vm/linker.scm (process-reloc): Subtract SECTION-OFFSET
when writing to BV.
(write-linker-object): Pass BV directly to the linker object writer.
(link-elf): When PAGE-ALIGNED? is false, call 'bytevector-slice' from
here. When it is true, return a procedure that takes a port and writes
to it, without having to allocate a bytevector for the whole ELF
container.
* module/language/bytecode/spec.scm (bytecode->value): Handle X being a
procedure instead of a bytevector.
(bytecode) <#:printer>: Likewise.
* test-suite/tests/linker.test (link-elf-with-one-main-section): Pass
#:page-aligned? #f.
This reduces the amount of memory used during linking and reduces the
number of copies to be done between bytevectors.
* module/system/vm/linker.scm (<linker-object>): Remove 'bv' field and
add 'size' and 'writer'.
(make-linker-object): Adjust accordingly.
(string-table-size): New procedure.
(link-string-table!): Remove.
(string-table-writer): New procedure.
(allocate-segment): Adjust 'make-linker-object' call.
(find-shstrndx): Call the 'linker-object-writer' of O.
(add-elf-objects): Adjust 'make-linker-object' call. Remove
'make-bytevector' allocations and move serialization to lazy 'writer'
procedures. Define 'segments' and 'add-header-segment!'. Return the
latter as the first value.
* module/system/vm/assembler.scm (make-object): Remove 'bv' parameter
and add 'size' and 'writer'.
(link-data): Remove 'make-bytevector' call and move serialization to
a lazy 'writer' procedure.
(link-text-object): Likewise.
(link-frame-maps): Likewise.
(link-dynamic-section): Likewise.
(link-shstrtab): Likewise.
(link-symtab): Likewise.
(link-arities): Likewise, and remove 'bytevector-append'.
(link-docstrs): Likewise.
(link-procprops): Likewise.
(link-debug): Likewise, and define 'copy-writer'.
* test-suite/tests/linker.test (link-elf-with-one-main-section): Adjust
accordingly.
* module/system/vm/assembler.scm (process-relocs): Remove 'buf'
parameter and turn into a pure function.
(patch-relocs!): New procedure. Perform the side effects previously
done in 'process-relocs'.
(link-text-object): Adjust accordingly.
Workaround for <https://bugs.gnu.org/57948>.
* module/system/vm/frame.scm (frame-call-representation): Treat a
binding as "unspecified" if its slot exceeds 'frame-num-locals'.
Locations are stored in tree-il records in "source vector" form, but
`location-string' was rendering these as <unknown-location>.
* module/system/base/message.scm (location-string): Support locations
passed as a file/line/column vector.
The code coverage function `coverage-data->lcov` has a documented
`modules` argument, however that was missing from the source. I have
added it so when supplied it only converts the coverage data for the
supplied modules. If not supplied it defaults the old behavour of
including all the modules currently loaded.
* module/system/vm/coverage.scm (coverage-data->lcov): Add #:modules
parameter and honor it.

NetBSD and pkgsrc have been using an empty vendor string since the
mid-'90s, such as x86_64--netbsd. pkgsrc has been carrying around a
workaround just the guile build for a long time. (Before that,
NetBSD omitted the vendor altogether, so if x86_64 existed then it
might have been `x86_64-netbsd', but that caused more problems.)
This change makes Guile accept an empty vendor string so workarounds
are no longer necessary.
* module/system/base/target.scm (validate-target): Allow empty vendor
string in GNU target triplets.
* test-suite/tests/cross-compilation.test ("cross-compilation"): Add
tests for "x86_64--netbsd".

Avoiding systematic conversion from source vectors to property alists
saves 20% on the final heap size of a process doing:
(compile-file FILE #:optimization-level 1)
where FILE is large.

* module/language/tree-il/analyze.scm (shadowed-toplevel-analysis): Use
'tree-il-src' instead of accessing the 'src' slot directly.
* module/system/vm/assembler.scm (link-debug): Adjust so PC can be
followed by a vector or an alist.
* configure.ac:
* Makefile.am (SUBDIRS): Replace bootstrap/ with stage0, stage1, and
stage2.
* am/bootstrap.am: Include all files and all rules.
* meta/build-env.in (GUILE_AUTO_COMPILE): Always turn off
auto-compilation. Take a GUILE_BOOTSTRAP_STAGE argument, which can be

* stage0/Makefile.am:
* stage1/Makefile.am:
* stage2/Makefile.am: New files.
496f69dba2 introduced C99 complex types in
libguile/foreign.h and (system foreign). Since these types are provided
conditionally in foreign.h based on autoconf tests they need to be used
conditionally in (system foreign) based on their presence.
* libguile/foreign.h (SCM_FOREIGN_TYPE_COMPLEX_FLOAT,
SCM_FOREIGN_TYPE_COMPLEX_DOUBLE): New enums.

This flag was set, but never used in Guile, and there was no documented
API to access it.
To check if an array is contiguous, use (array-contents <> #t).
* libguile/arrays.h (scm_i_raw_array): New function.
SCM_I_ARRAY_CONTIGUOUS, SCM_SET_ARRAY_CONTIGUOUS_FLAG,
SCM_CLR_ARRAY_CONTIGUOUS_FLAG, SCM_I_ARRAY_CONTP: Remove.
scm_t_array_dim: Declare here, not in array-handle.h.
SCM_I_ARRAY_NDIM: Shift by one bit since the contp flag isn't there
anymore.
* module/syste/vm/assembler.scm: Match removal of contp flag.
* libguile/arrays.c (scm_i_make_array): Reuse scm_i_raw_array.

pass at -O1.
This enables the compilation from "manually" written Tree-IL to
bytecode. See also <https://bugs.gnu.org/45131>.
* system/base/compile.scm (read-and-compile)[(joint #f)]<? eof-object?>:
Join exps using the default joiner for to.
<exp>: Compute compiler for to.
* test-suite/test/compiler.test ("read-and-compile tree-il"): New test.
* libguile/intrinsics.h:
* libguile/intrinsics.c (lookup_bound_public, lookup_bound_private): Two
new intrinsics.
(scm_bootstrap_intrinsics): Wire them up.
* libguile/jit.c (compile_call_scm_from_scmn_scmn):
(compile_call_scm_from_scmn_scmn_slow):
(COMPILE_X8_S24__N32__N32__C32): Add JIT support for new instruction
kind.
* libguile/vm-engine.c (call-scm<-scmn-scmn): New instruction, takes
arguments as non-immediate offsets, to avoid needless loads and register
pressure.
* module/language/cps/effects-analysis.scm: Add cases for new
primcalls.
* module/language/cps/compile-bytecode.scm (compile-function): Add new
primcalls.
* module/language/cps/reify-primitives.scm (cached-module-box): If the
variable is bound, call lookup-bound-public / lookup-bound-private as
appropriate instead of separately resolving the module, name, and doing
the bound check.
* module/language/tree-il/compile-bytecode.scm (emit-cached-module-box):
Use new instructions.
* module/system/vm/assembler.scm (define-scm<-scmn-scmn-intrinsic):

case, the function must be well-known and callers are responsible for
calling with the appropriate arity.
* module/language/cps/compile-bytecode.scm: Emit "unchecked-arity" for
$kargs following $kfun.
* module/system/vm/assembler.scm: Adapt.
When using automake and libtool to build DLLs on Cygwin, libtool
will rename libXXX to cygXXX. 'load-foreign-library' should
emulate libltdl behavior and search for DLLs using that convention.
* module/system/foreign-library.scm (lib->cyg): new helper function
(load-foreign-library): add rename-on-cygwin? option to rename
libraries using Cygwin semantics
* test-suite/tests/foreign.test: new test section 'lib->cyg'
* doc/ref/api-foreign.text: document new rename-on-cygwin? option
for load-foreign-library
* doc/ref/posix.texi (File System): Update to document mkstemp only.
* libguile/filesys.c: Make a mkstemp that doesn't modify the input
template. Instead the caller has to get the file name from
port-filename.
(scm_mkstemp): Use the new mkstemp to implement mkstemp!. Can't
deprecate yet though as the replacement hasn't been there for long
enough.
* libguile/posix.c (scm_tempnam): Update to mention mkstemp instead.
* module/system/base/compile.scm (call-with-output-file/atomic): Use
mkstemp.
* test-suite/tests/posix.test:
* test-suite/tests/r6rs-files.test: Use mkstemp.
* NEWS: Update.
* module/system/vm/assembler.scm (intern-constant, link-data): Write the
vector representation of source instead of the alist. Saves a lot of
heap size, object file size, and init time when serializing syntax
objects with source.
* module/system/vm/assembler.scm (<asm>, make-assembler)
(intern-constant, emit-init-constants): Instead of loading a dependent
value each time it's needed in the relocation procedure, eagerly patch
values when they are created. Allows keeping values in registers, which
decreases code size.
