2017-04-18newlib: remove __infinity{f,ld} constantsCorinna Vinschen3-31/+4
previous commit 4c90db7bc89e7fa1077025fefdd58269dc71a6ac introduced a compile time error because libm/common/s_infconst.c used the remove __fmath, __dmath, and __ldmath union types. Since this is very old, and unused for a very long time, just drop the file and thus the __infinity constants entirely. Exception: Cygwin exports __infinity from the beginning. There's a very, VERY low probability that any existing executable or lib still uses this constant, but we just keep it in for backward compat, nevertheless.

2016-10-25Fix pdf build failure with texinfo 6.1.0Thomas Preudhomme1-1/+0
Hi, make pdf on Ubuntu 16.04 fail with: newlib/libc/libc.texinfo:9: Missing @endcsname inserted. After a lot of fiddling the reason appears to be the combination of concept and function index despite a lack of concept index entries. Arguably texinfo should not error in that case but here we are, newlib will fail to build its documentation on some systems because of this. Since libc.texinfo only contains function index entries this patch simply removes the combination of indices. It does the same for libm.texinfo which has concept index entries but no function index entries. Tested by running make pdf, make dvi, make info and make html successfully. libc.pdf appears to have only one index as expected. == Proposed commit message == Fix pdf build failure with texinfo 6.1.0 as provided in Ubuntu 16.04. Index combination in libc.texinfo and libm.texinfo fails because both file have only one type of index entries. Removing index combination is thus harmless and solves the problem. Is this ok for master? Best regards, Thomas

2016-02-17Define the newlib version macros in one place: _newlib_version.h.Pieter du Preez4-24273/+37
Currently, the newlib version information needs to be updated in two places: - newlib/acinclude.m4 - newlib/libc/include/sys/features.h The goal of this patch is to: - supply a single location for defining the newlib version information: newlib/acinclude.m4 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__ This is in line with what gcc does for its version macros. See: https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__ and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h, to the newly generated newlib/_newlib_version.h file. Additionally, the __NEWLIB_PATCHLEVEL__ macro was created, for completeness. In order to stay backwards compatible, newlib/_newlib_version.h gets included by newlib/newlib.h and newlib/libc/include/sys/features.h. Note: This patch does _not_ include the modifications to the following files, as these should all be generated any way. *Makefile.in, *aclocal.m4, *configure stamp-* files Signed-off-by: Pieter du Preez <pdupreez@gmail.com>

2015-12-09Check for 64 FP instructions availability in libm before using themThomas Preud'homme6-6/+6
Currently, double precision math functions in newlib/libm/machine/arm detect whether neon instructions can be used for double precision computation by checking the architecture version (>= 8) and the availability of floating-point instructions. However, these instructions would not be available if targeting fpv5-sp-d16 as the FPU, which by definition does not have 64bit float instructions. This patch adds a check that __ARM_FP advertises 64bit float instructions. * libm/machine/arm/s_ceil.c: Also check that 64bit FP instructions are available in the guard. * libm/machine/arm/s_floor.c: Likewise. * libm/machine/arm/s_nearbyint.c: Likewise. * libm/machine/arm/s_rint.c: Likewise. * libm/machine/arm/s_round.c: Likewise. * libm/machine/arm/s_trunc.c: Likewise.
2015-11-12doc: Fix some inconsistent QUICKREF linesJon Turney5-5/+10
makedoc defines a command as 'all upper case, and alone on a line'. A few QUICKREF lines currently violate this by having some additional text after the QUICKREF. So, currently, these lines are treated as an unknown command. This is benign as QUICKREF currently does nothing but produce some ignored output on stderr. I'm not sure what the intent of QUICKREF is. 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * libm/mathfp/s_acos.c: Fix QUICKREF. * libm/mathfp/e_acosh.c: Ditto. * libm/math/w_asin.c: Ditto. * libm/mathfp/e_acosh.c: Ditto. * libm/mathfp/s_acos.c: Ditto.
