* Newlib build is broken if configured with nano-malloc and non-reentrant ↵Игорь Веневцев2016-02-081-4/+6

* Check for 64 FP instructions availability in libm before using themThomas Preud'homme2015-12-097-6/+16
| | | | | | | | | | | | 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.

* [ARM] Refactor strlen.c #if nesting.Marcus Shawcroft2015-11-132-26/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch flattens the condition code selection used in strlen in an attempt to make the guarding condition for each alternative implementation clearer and to structure the logic in a manner that makes it easier to maintain complementary logic between the alternative 'C' and assembler implementations. Tested by building newlib and comparing libc.a binaries before and after for all permutations of: Architectures: armv4 armv4t armv5 armv5t armv5te armv6 armv6j armv6k armv6z armv6kz armv6t2 armv6-m armv6s-m armv7 armv7-a armv7ve armv7-r armv7-m armv7e-m armv8-a iwmmxt iwmmxt2 ISAs: thumb arm Optimization Levels: Os O2 Excluding: armv6s-m -mthumb armv6-m -mthumb armv6zk -mthumb armv6z -mthumb armv6k -mthumb armv6j -mthumb

* Fix multilib libgloss selection.Marcus Shawcroft2015-11-122-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression testing newlib in conjunction with libgloss and --enable-multilib can result in incompatible multilib versions of newlib and libgloss being used during link. This manifests on ARM target when newlib regression is run using a GCC configured using --with-multilib-list=aprofile With this configuration many of the multilib variants built are mutually incompatible. The issue is that the newlib dejagnu foo iterates each multilib variant and correctly chooses the appropriate newlib variant but always chooses the root/base libgloss variant. The implementation of newlib/testsuite/lib/flags.exp contains the following fragment: set target_build_path "$objdir/$multibuildtop.." The effect of this fragment is to explicitly select the root version of libgloss, irrespective of the current multilib. Digging around in VC it appears that the original implementation of multlib magic came into the tree back in 2002 with: 6e9d950a (Thomas Fitzsimmons 2002-05-01 17:06:25 +0000 39) In this initial version of multilib support, newlib was multilib capable, but libgloss was not multilib capable, hence the necessity to explicitly select the root libgloss version. Subsequently flags.exp was modified to support out of tree testing: cec1d3b4 (Jeff Johnston 2005-07-05 00:11:50 +0000 25) This change is orthogonal to this issue, its effect is to exit early in none multilib configurations. Subsequently libgloss gained --enable-multilib support, the relevant change is: https://sourceware.org/ml/newlib/2006/msg00440.html commit 00a4b31ad08aef361c5d74125ece410b4c285975 Author: Jeff Johnston <jjohnstn@redhat.com> Date: Wed May 10 20:51:41 2006 +0000 This change enabled multilib support throughout libgloss, but ommitted to adjust the flag.exp behaviour which anchors the libgloss multilib selection to the base version. The attached patch adjusts flags.exp to select the current multilib variant of libgloss. 2015-11-06 Marcus Shawcroft <marcus.shawcroft@arm.com> * testsuite/lib/flags.exp (libgloss_link_flags): Drop multilibtop from target_build_path.
* makedoc: Don't interpret license text as a commandJon Turney2015-11-122-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | Align makedoc's iscommand() with it's documentation, and don't allow commands to contain a space. A command is a line containing only a sequence of capital letters or '_', followed by optional spaces. This prevents "IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE" (the only line in the license text which consists of only capitals and spaces, without any punctuation) from being interepreted as a makedoc command, leading to: "Can't find IMPLIED" "warning, IMPLIED is not recognised" being emitted by makedoc, (which is normally un-noticed because makedoc's stderr is redirected to a .ref file) 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * doc/makedoc.c (iscommand): Only allow commands to have trailing spaces, not space separated words.
