Status of newlib toolchain targets

Status of newlib toolchain targets

[Yaakov Selkowitz]

With binutils-2.25.1, gcc-5.3.0, and newlib-2.3.0.20160226:

iq2000-elf (PR64400), m32c-elf (PR64375), and mep-elf (PR64402) still do 
not build; the latter has been declared obsolete.

arm-eabi newlib requires a small include path fix; will post shortly.

cr16-elf and lm32-elf require a patch to include newlib-stdint.h:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-newlib-stdint.patch
(Nick: I see cr16 committed but not lm32?)

frv-elf requires r222519:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-frv-r222519.patch

m32r-elf requires r226445:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-m32r-attributes.patch

moxie-elf binutils requires some post-2.25 commits:
https://raw.githubusercontent.com/cygwinports-extras/cross-binutils/master/2.25-moxie-opcodes.patch

v850-elf requires a patch to remove a feature added to binutils 
post-2.25, and a backport of r232451:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-v850-msoft-float.patch
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-v850-PR65501.patch

With the above fixes, the following targets build successfully:

aarch64-elf aarch64_be-elf arm-eabi bfin-elf cr16-elf cris-elf 
epiphany-elf fido-elf fr30-elf frv-elf h8300-elf i386-elf ia64-elf

Fantastic and well done.

When is the next newlib snapshot due? When one appears I can start to 
see how RTEMS goes.

True - but for some reason the patch *is* in the current gcc sources.

I suspect a snafu - I probably checked it in as part of a commit for a
different patch and nobody noticed, not even me.  Doh.  Personally I am
not sure if it is worth the noise to correct the mistake.

Cheers

I just started a build of tools for all RTEMS targets using the
binutils-gdb, newlib, and gcc master's. When those are finished,
I will try RTEMS itself.

Assuming RTEMS builds ok using the master. :)

If this test sweep is OK, once we bump our tools to the next snapshots
for gcc and newlib, I will get someone to run the FACE Conformance Test
Suite and see if it is happy with the feature test changes.

Just noticed that sparc64-elf sometimes fails with the following:

I'm still not sure why sometimes it does compile though.

Status of newlib toolchain targets, April 2016

[Yaakov Selkowitz]

With binutils-2.26, gcc-5.3.0, and newlib-2.4.0:

For C99-in-C++ support, two patches are required:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-newlib-funcs.patch
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-glibcxx-use-c99.patch

iq2000-elf (PR64400), m32c-elf (PR64375), and mep-elf (PR64402) still do 
not build; the latter has been made obsolete in GCC 6.

cr16-elf and lm32-elf gcc require a patch to include newlib-stdint.h:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-newlib-stdint.patch

frv-elf gcc requires r222519:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-frv-r222519.patch

m32r-elf gcc requires r226445:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-m32r-attributes.patch

sparc64-elf newlib sporadically fails to build:
https://sourceware.org/ml/newlib/2013/msg00740.html

tic6x-elf binutils requires the fix for PR gas/19614:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=bd5608dcc6a76876db06b1af1852252a4282aa2f

v850-elf gcc requires a backport of r232451:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-v850-PR65501.patch

With the above fixes, the following targets build successfully and with 
_GLIBCXX_ENABLE_C99 (so e.g. std::to_string and std::stod are now 
available with -std=c++11):

aarch64-elf aarch64_be-elf arm-eabi bfin-elf cr16-elf cris-elf
