* libguile/strports.c (scm_mkstrport): Use UTF-8; ignore
%default-port-encoding. Rename 'str_len' and 'c_pos' to
'num_bytes' and 'c_byte_pos'. Interpret 'pos' argument
as a character index instead of a byte index.
* module/ice-9/boot-9.scm (%cond-expand-features): Add srfi-6 to the
list of core features.

non-compliant behavior of string ports with regard to encoding.

%default-port-encoding before creating string ports.
* test-suite/tests/r6rs-ports.test ("lookahead-u8 non-ASCII"): Don't set
%default-port-encoding before creating string ports.
("put-bytevector with UTF-16 string port", "put-bytevector with
wrong-encoding string port"): Use 'set-port-encoding!' to set the
string port encoding.

the string port encoding.
("truncated-print"): Use 'pass-if-equal'.

[utf-8]", "peek-char [utf-16]"): Remove tests.

"wrong encoding, error", "wrong encoding, substitute",
"wrong encoding, escape"): Use 'set-port-encoding!' to set the
string port encoding.
("%default-port-encoding, wrong encoding"): Rewrite to use
a file port instead of a string port.
According to the new benchmarks, this leads a 5% speed improvement when
reading small strings, and a 27% improvement when reading large strings.
* libguile/read.c (READER_STRING_BUFFER_SIZE): Change to 128; update
comment to mention codepoints.
(scm_read_string): Make `str' a list of strings, instead of a string.
Store characters read in buffer `c_str'. Cons to STR when C_STR is
full, and concatenate/reverse at the end.
* benchmark-suite/benchmarks/read.bm (small, large): New variables.
Set %DEFAULT-PORT-ENCODING to "UTF-8".
("read")["small strings", "large strings"]: New benchmarks.
* benchmark-suite/benchmarks/arithmetic.bm:
* benchmark-suite/benchmarks/r6rs-arithmetic.bm: Use #e1e7 for the
iteration count, instead of the flonum 1e7.

local to the "rdelim" benchmark prefix.
(large-string): New procedure.
(%latin1-port, %utf8/ascii-port, %utf8/wide-port): Use it.

["+", "-"]: New benchmarks.
* libguile/vm-i-scheme.c (INUM_MAX, INUM_MIN): New macros.
(add1, sub1): Add/subtract without untagging the operand. This leads
to a 44% run time improvement compared to the previous
implementation.
* libguile/vm.c: Include <stdint.h>.
* test-suite/tests/numbers.test ("1+", "1-"): Add tests for
MOST-POSITIVE-FIXNUM, resp. MOST-NEGATIVE-FIXNUM, for 32-bit and
34-bit values thereof.
* benchmark-suite/benchmarks/arithmetic.bm: New file.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add it.
This makes `peek-char' 40x faster on a port whose encoding is
faster on a UTF-8 port containing multi-byte codepoints.
The `xml->sxml' procedure is 4x faster on a 2.7 MiB XML file.
* libguile/ports.c (get_codepoint): New procedure, moved here from
`scm_getc', with the additional BUF and LEN parameters.
(scm_getc): Use it.
(scm_peek_char): Use it instead of the `scm_getc'/`scm_ungetc'
sequence.

"peek-char [utf-8]"]: New tests.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add
`benchmarks/ports.bm'.
* benchmark-suite/benchmarks/ports.bm: New file.
According to `write.bm', this makes `write' 2.6 times faster for strings.

* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add
`benchmarks/write.bm'.

iterations from 300 to 12000.

iterations from 1100 to 20000, and "pad" from 6800 to 34000.
* benchmark-suite/benchmarks/uniform-vector-read.bm
("uniform-vector-read!"): Increase "uniform-vector-write" iterations
from 500 to 4000, and "uniform-vector-read!" from 500 to 20000.
* benchmark-suite/benchmarks/bytevectors.bm: Add "coding: latin1"
comment where Guile will find it.
* benchmark-suite/benchmarks/chars.bm: Ditto.
* benchmark-suite/benchmarks/srfi-13.bm: Ditto.
* benchmark-suite/benchmarks/read.bm ("read"): Divide numbers of
iterations by 10, so that the benchmarks complete within a few
minutes.
* benchmark-suite/lib.scm (benchmark): Use `run-benchmark' in macro
definition, not `,run-benchmark'.
* benchmark-suite/benchmarks/0-reference.bm,
benchmark-suite/benchmarks/continuations.bm,
benchmark-suite/benchmarks/if.bm,
benchmark-suite/benchmarks/logand.bm: Add define-module.
* benchmark-suite/results/neil-arudy: New file, containing benchmark
results from my computer.
Test more of the positive paths. Add test for string-prefix-ci?
string-suffix-ci? and string-hash-ci. Update the counts per test
to give approximately the same bench/interp time for each test for
1.8.7.
* benchmark-suite/benchmarks/srfi-13.bm: update benchmarks
* benchmark-suite/benchmarks/subr.bm (hook1, hook3): New variables.
("subr invocation")("generic subr with rest arg", "generic subr with
rest arg and 3+ parameters"): New benchmarks.
("subr application")("generic subr with rest arg", "generic subr with
rest arg and 3+ parameters"): New benchmarks.
from the test-suite directory, renamed and adapted for use with
benchmarks.
* benchmarks/logand.bm, benchmarks/continuations.bm,
benchmarks/if.bm: Added as initial fairly stupid examples for
benchmarks.
