* module/texinfo.scm (read-char-data): Preserve newlines in @example and
similar environments in the case when the next line starts with an @.
* test-suite/tests/texinfo.test ("test-texinfo->stexinfo"): Add a test.
* module/statprof.scm (gcprof): No need to reset in gcprof; the fresh
profiler state and the parameterize handle that. Fix mistaken
set-vm-trace-level! as well.
* module/statprof.scm (<state>): The sampling frequency is actually a
period; label it as such, and express in microseconds instead of as a
pair. Likewise for remaining-prof-time.
(fresh-profiler-state): Adapt.
(reset-sigprof-timer): New helper.
(profile-signal-handler): Use the new helper.
(statprof-start): Use the new helper.
(statprof-stop): Here too.
(statprof-reset): Adapt to <state> change.
(gcprof): Set remaining prof time to 0.
* module/language/cps/simplify.scm (prune-continuations): Prune
continuations as a post-pass with a fresh DFG. Using a
pre-eta-conversion DFG as we were doing before missed some cases.
* module/statprof.scm (profile-signal-handler): Don't bother detecting
if we were in a count-call call or not; it doesn't matter, and we
should accumulate time in any case.
* module/statprof.scm (fresh-profiler-state): accumulated-time and
gc-time-taken are in jiffies, not seconds, so they are exact.
(statprof-accumulated-time): Divide by 1.0 so that we get a flonum.
Also refactor use of assq to get the gc-time-taken.
* module/language/cps/simplify.scm (compute-eta-reductions): Avoid
trying to eta-reduce a jump-to-self, as in (let lp () (lp)). This
caused the compiler to hang.
* module/statprof.scm (get-call-data, sample-stack-procs): Take the
state as an argument.
(profile-signal-handler, count-call, statprof-proc-call-data)
(gcprof): Adapt.
* module/statprof.scm (statprof-reset, statprof-fold-call-data):
(statprof-proc-call-data, statprof-accumulated-time):
(statprof-sample-count): Refactor some things to use statprof-active?
instead of checking the profile level manually.
* module/statprof.scm (fresh-profiler-state): New helper.
(ensure-profiler-state): Use it.
(accumulate-time): No need to add 0.0 here.
(statprof-reset): Create a new state instead of mutating the existing
one.
* module/statprof.scm (existing-profiler-state): New helper, gets the
profiler state or fails if there is no state.
(sample-stack-procs, profile-signal-handler, count-call)
(statprof-fold-call-data, statprof-proc-call-data)
(statprof-call-data->stats, statprof-display)
(statprof-display-anomolies, statprof-accumulated-time)
(statprof-sample-count, statprof-fetch-stacks)
(statprof-fetch-call-tree): Use the new helper.
(statprof-active?): Don't create a state if there isn't one already.
* module/statprof.scm (<state>, profiler-state, ensure-profiler-state):
A mostly-mechanical refactor to encapsulate profiler state in a
parameter and a record instead of global variables.
* module/ice-9/boot-9.scm (catch): Signal an early error if the handler
or pre-unwind handler types aren't right. This is more important than
it was, given that we dispatch on type now when finding matching catch
clauses.
* libguile/vm.c (vm_expand_stack): Use the standard
scm_report_stack_overflow to signal stack overflow. This will avoid
running pre-unwind handlers.
* libguile/throw.h: Move scm_report_stack_overflow here.
* libguile/throw.c (catch): Define a version of catch in C.
(throw_without_pre_unwind): New helper. Besides serving as the
pre-boot "throw" binding, it allows stack overflow to throw without
running pre-unwind handlers.
(scm_catch, scm_catch_with_pre_unwind_handler)
(scm_with_throw_handler): Use the new catch in C.
(scm_report_stack_overflow): Moved from stackchk.c; throws an
unwind-only exception.
* libguile/stackchk.h:
* libguile/stackchk.c: Remove the scm_report_stack_overflow bits.
* libguile/throw.c (scm_init_throw): Define %exception-handler here.
* module/ice-9/boot-9.scm (%eh): Use the incoming %exception-handler,
and then delete it. This way we should be able to do unwind-only
exceptions from C.
* module/ice-9/boot-9.scm: Reimplement catch, throw, and
with-throw-handler in such a way that the exception handler is
threaded not through the exception-handling closures, but through a
data structure in the exception-handler fluid. This will allow us to
do unwind-only exception dispatch on stack overflow.
* module/ice-9/boot-9.scm: Move error-handling initialization after
psyntax initialization. Only "throw" is used before psyntax, and both
throw and catch have pre-boot variants in C.
* module/language/tree-il/peval.scm (peval): When going to peval a call
whose operator isn't just a lambda but is a let-bound lambda, as one
bound via define-inlinable, don't create a new counter if the lambda
is only referenced once in the source. Avoids needless failure to
inline once-referenced procedures.
* test-suite/tests/peval.test ("partial evaluation"): Wheeeee
* libguile/loader.c (load_thunk_from_memory): Only load PT_LOAD
segments, as libc does. The PT_DYNAMIC segment should be inside some
other PT_LOAD segment.
* module/system/vm/linker.scm (segment-kind): Give the .dynamic segment
PT_LOAD kind, so that it is written in a PT_LOAD segment.
(count-segments): Add one if there is a SHT_DYNAMIC segment.
(allocate-segment): Set the paddr to the addr, as binutils do.
(record-special-segments): New routine, to write out special segments
like PT_DYNAMIC.
(allocate-elf): Call record-special-segments.
* module/system/vm/elf.scm: Define more ABI types and ELF object types.
Export the ABI, object type, and machine type values.
* module/system/vm/linker.scm (<linker-reloc>, process-reloc): Allow
rel32/1 relocs.
(add-elf-objects, allocate-elf, link-elf): Allow the user to set an
ABI, type, and machine-type.
* module/language/cps/prune-top-level-scopes.scm: New pass, to prune
unneeded "cache-current-module!" forms.
* module/language/cps/compile-bytecode.scm:
* module/Makefile.am: Add the new pass to the build and enable by
default.
This commit also renames uniform-vector-element-type-code to
array-type-code.

instead of uniform-vector?; the latter could be true for shared arrays
with non-zero lower bounds.
