2018-03-14Fix alloc_align and alloc_size macros for multiple argumentsYaakov Selkowitz2-4/+4
https://sourceware.org/ml/newlib/2018/msg00263.html This is a follow-up to commit 4564b30f331a067e71b25308ac7c8a85ceb4b122. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
2018-03-14ctype: align size of category bit fields to small targets needsCorinna Vinschen1-2/+2
E.g. arm ABI requires -fshort-enums for bare-metal toolchains. Given there are only 29 category enums, the compiler chooses an 8 bit enum type, so a size of 11 bits for the bitfield leads to a compile time error: error: width of 'cat' exceeds its type enum category cat: 11; ^~~ Fix this by aligning the size of the category members to byte borders.

This reverts commit e98d3eb3eb9b6abd897e102031a14b7057641a65. It has accidentally included some work in progress.
2018-03-14fix/enhance Unicode table generation scriptsThomas Wolff2-18/+53
Scripts do not try to acquire Unicode data by best-effort magic anymore. Options supported: -h for help -i to copy Unicode data from /usr/share/unicode/ucd first -u to download Unicode data from unicode.org first If (despite of -i or -u if given) the necessary Unicode files are not available locally, table generation is skipped, but no error code is returned, so not to obstruct the build process if called from a Makefile.

2018-03-13towctrans_l: Always return a value from helper functionsCorinna Vinschen1-19/+49
touupper and toulower didn't return a value in all cases. Worse, this only broke Cygwin when building without optimization for debug purposes. Why GCC neglects to notice this is a mystery. While at it, fix formatting. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2018-03-12make target for explicit Unicode data tables generationThomas Wolff1-0/+9
Run 'make unidata' in newlib target directory to generate Unicode data tables for libc functions wcwidth, tow* and isw*.
2018-03-12character data generationThomas Wolff3-0/+237
2018-03-12use generated character dataThomas Wolff38-2681/+439
The tow* functions use an included case conversion table which can be generated from Unicode data. The isw* functions use a character categories table (provided by categories.c) which can be generated from Unicode data. Delegation between current-locale and specific-locale-dependent functions was reverted towards the generic locale-dependent functions (*_l.c); this is however only relevant on systems with non-Unicode wide character locales, thus not on Cygwin.
2018-03-12generated character category data, Unicode 10.0Thomas Wolff2-0/+2115
Table categories.t and tag enumeration categories.cat provide character class data for most of the isw* functions. These data are generated from Unicode data.
2018-03-12generated case conversion data, Unicode 10.0Thomas Wolff1-0/+304
Table caseconv.t provides case conversion data for the tow* functions, especially towupper and towlower. These data are generated from Unicode data.

2018-03-12use generated width dataThomas Wolff1-126/+24
2018-03-12generated width data, Unicode 10.0Thomas Wolff3-0/+201
These tables provide character width properties for use by the wcwidth/wcswidth functions. They are generated from Unicode.
2018-03-06RTEMS: Use int for _CLOCKID_T_Sebastian Huber1-0/+3
Linux and FreeBSD use int as well. In addition, this fixes an Ada incompatiblity problem on 64-bit targets. See also GCC: gcc/ada/libgnarl/s-osinte__rtems.ads Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

2018-03-05Locale modifier @cjkwide to adjust ambiguous-width in non-CJK localesThomas Wolff1-16/+23
Locale modifier @cjkwide makes Unicode "ambiguous width" characters wide. So ambiguous width characters can be enforced to have width 2 even in non-CJK locales. This gives e.g. users of "Powerline symbols" the opportunity to adjust their width to the desired behaviour (and the behaviour apparently expected by some tools) without having to set a CJK locale and without losing consistence of terminal character width with wcwidth/wcswidth locale width.

2018-01-25Disable powf/log2?f/exp2?f optimization for single-precision Arm FPUThomas Preudhomme1-1/+3
New optimized powf, logf, log2f, expf and exp2f yield worse performance on Arm targets with only single precision instructions because the double precision arithmetic is then implemented via softfloat routines. This patch uses the old implementation when double precision instructions are not available on Arm targets. Testing: Built newlib with GCC's rmprofile Arm multilibs and compared before/after -> only the above functions are changed and calls to them (name change from logf to __ieee754_logf and similar). Testing the changed function on a panel of values yields the same result before the original patches to improve them and after this one. Double checking the performance by looping the same panel of values being tested on Arm Cortex-M4 does show the performance regression is fixed.
