| | | | | | | | | This is a NetBSD-specific detail which does not apply to Newlib, causing linking issues in certain scenarios: https://cygwin.com/ml/cygwin/2018-01/msg00189.html Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Disable powf/log2?f/exp2?f optimization for single-precision Arm FPUThomas Preudhomme2018-01-251-1/+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.

* Fix syntax error in exit.cOrlando Arias2018-01-191-1/+1
| | | | | | This patch fixes a syntax error in exit.c that was introduced during the ANSI-fication of newlib. The patch fixes a compile-time issue that arises when newlib is configured with the --enable-lite-exit feature.

* newlib: vfwscanf: fix negation bug in %[ conversionCorinna Vinschen2017-12-041-1/+1
| | | | | | | | | | | Old BSD bug: While ^ is recognized and the set of matching characters is negated, the code neglects to increment the pointer pointing to the matching characters. Thus, on a negation expression like %[^xyz], the matching doesn't only stop at x, y, or z, but incorrectly also on ^. Fix this by setting the start pointer after recognizing the ^.

* newlib: vf[w]scanf: Drop width computation mixupCorinna Vinschen2017-12-012-70/+44
| | | | | | | | | | | | | | | | | | | The width value keeps the maximum field width. This is the maximum field width of the *input*. It's *never* to be used in conjunction with the number of bytes or characters written to the output argument. However, especially in vfwscanf, the code is partially taken from NetBSD which erroneously subtracts the number of multibyte chars written to the argument from the width variable, thus potentially subtracting up to MB_CUR_MAX from width for a single character in the input stream. To make matters worse, the previous patch adding %m added basically the same mistake for 'c' type input. Fix it. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
