v2 cover Upgrade ARC port to new toolchain

These three patches upgrade the ARC toolchain to GCC 4.8 and Binutils 2.23.2. This fixes multiple issues (including most autobuilder failures from the past couple of weeks).

v2:
* Remove gcc 4.4.7 patch
* Fix whitespace in fix_branch_out_of_range.patch
* Remove binutils 2.19-arc dependencies (not required anymore)
* Fix gcc 4.8-arc dependencies (host-flex, host-bison still required :-( )

Mischa Jonker (3):
uclibc, eglibc: remove REALLY_NOSTDLIB references
arc: binutils: Go from 2.19-arc to 2.23.2-arc
arc: gcc: Go from 4.4.7 to 4.8 for ARC

PATCH v2 1/3 uclibc, eglibc: remove REALLY_NOSTDLIB references

These were required with ARC gcc 4.4.7; ARC gcc 4.8 has been changed to behave the same as other architectures with -nostdlib, making this option obsolete.

PATCH v2 3/3 arc: gcc: Go from 4.4.7 to 4.8 for ARC

In reply to Mischa Jonker

This fixes multiple issues, including:
- 'operand out of range' errors (due to defaulting to medium calls instead of short calls)
- library dependencies that were not being found

v2 cover Upgrade ARC port to new toolchain

In reply to Mischa Jonker

Dear Mischa Jonker,

Quoted 3 lines · Mischa Jonker

These three patches upgrade the ARC toolchain to GCC 4.8 and Binutils 2.23.2. This fixes multiple issues (including most autobuilder failures from the past couple of weeks).

Thanks!

While you're at it, have you followed the recent changes on floating point support for ARM? How does floating point support works on ARC? Completely soft-float? Hard float is possible? Always the same FPU?

Thanks!

Thomas

v2 cover Upgrade ARC port to new toolchain

Hi Thomas,

Quoted 2 lines

While you're at it, have you followed the recent changes on floating point support for ARM?

I saw the mails, but I haven't studied them in detail.

Quoted 2 lines

How does floating point support works on ARC?
Completely soft-float? Hard float is possible? Always the same FPU?

For the current generation of cores (ARC700 series for Linux) we do not really have an 'FPU'. The ARC cores have the possibility of adding various extensions, and for floating point we happen to have 4 different kinds of extensions: spfp-compact, dpfp-compact, spfp-fast, dpfp-fast. In reality, these are just ADD, SUB and MUL instructions, the rest still needs to happen in software. The single and double precision extensions can be combined so both are supported in the same core. The fast and compact variants relate to the speed and the number of gates/area; I think they share the same opcode space.

I think right now it is more important to focus on getting most packages to build; after that I will look into the best way to make a toolchain + libraries tailored to the exact core configuration: the FPU is not the only thing that is configurable; you can have a variable set of registers, different types of multipliers, etc, etc.

If I were to add this configurability somewhere, do you think that CTNG would be the right place, or Buildroot?

Thanks,

Mischa
