I was using arm-eabi builds on Linaro Android 4.9 toolchain 2014.06.
I've just downloaded 2014.07 and found out there is not an arm-eabi
toolchain.
I need arm-eabi to build Linux kernels and arm-none-eabi toolchain from
here:
http://releases.linaro.org/14.07/components/toolchain/binaries/gcc-linaro-a…
is not capable of building LTO kernels.
Error pops up : "cc1: error: -fno-fat-lto-objects are supported only with
linker plugin"
TL;DR, I need arm-eabi builds from Linaro Android toolchains.
arm-none-eabi builds are not built with linker plugin enabled.
Short week (Friday off)
== Progress ==
* GCC trunk cross-validation (2/10)
- catch up with backlog, reported newly introduced FAILs
- analyzed logs of spurious failures, improved reporting of such cases
- the script will know send a separate email with the svn ids
it has selected for validation, to help fill the backports spreadsheet
* Infrastructure (2/10)
- started deployment of past releases to help us quickly
reproduce/investigate bug reports
- 14.* binary releases deployed on toolchain64 (/work/toolchains)
- automation not yet possible because of problem with the lab
internal squid proxy preventing the download of
http://releases.linaro.org/14.07/components/toolchain/binaries for
parsing
- started deployment of past toolchains built from the source
releases using cbuild2 but ran into build problems
* Neon intrinsics tests (1/10)
* Misc (conf calls, meetings) (3/10)
- 1-1 calls to get feedback after Cauldron+Sprint
- a bit of bugzilla triage
- backports reviews for 14.08 release
== Next ==
Holidays, back on Aug 18th
Hi Linaro-toolchain team,
I notice that the Linaro toolchain binary only support hard-float. We have a platform which is ARMv7 based does not support VFP.
Could you generate toolchain binary for ARmv7 that allows soft-float?
Thanks,
Joel
The Linaro Toolchain Working Group (TCWG) announces the 2014.07-1 release
of the Linaro GCC 4.9 source package. This is a respin of the 2014.07
release which
contained a backport of a revision that is only relevant to trunk.
Changes in this GCC source package release are:
* Updates to GCC 4.9.1 (svn212635)
* Revert backport of [AArch32] Fix PR target/61154.
Please find the original 2014.07 release notes below:
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.07
stable release of the Linaro GCC 4.9 source package.
Linaro GCC 4.9 2014.07 is the fourth Linaro GCC source package release in the
4.9 series. It is based on FSF GCC 4.9.1+svn212419 and includes performance
improvements and bug fixes.
With the imminent release of ARMv8 hardware and the recent release of the
GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and
performance of the compiler as the FSF GCC compiler approaches version 4.9.1.
The Linaro TCWG will provide monthly stable[1] source package releases until
FSF GCC 4.9.1 is released. At that point Linaro GCC 4.9 will merge in
FSF GCC 4.9.1 and, release Linaro GCC 4.9.1, and then return to a schedule of
stable quarterly releases and monthly engineering[2] releases.
Interesting changes in this GCC source package release include:
* Updates to GCC 4.9.1-pre+svn212419
* Backport of [AArch32] Wrap long literals in HOST_WIDE_INT_C in
aarch-common.c
* Backport of [AArch32] Rewrite TLC Intrinsics.
* Backport of [AArch32] Remove vzip, vuzp, vtrn builtins and cleanup
* Backport of [AArch32] Use enum name instead of integer value for
PARAM_SCHED_PRESSURE_ALGORITHM.
* Backport of [AArch32] Vectorise bswap*
* Backport of [AArch32] Fix PR/61331
* Backport of [AArch32] Fix PR target/61154
* Backport of [AArch32] Use mov_imm type for movw operations consistently
* Backport of [AArch32] Remove XFmode from ARM backend.
* Backport of [AArch64] Rewrite REV Intrinsics.
* Backport of [AArch64] Implement HARD_REGNO_CALLER_SAVE_MODE.
* Backport of [AArch64] Support tail indirect function call.
* Backport of [AArch64] Fix stack protector for ILP32
* Backport of [AArch64] ILP32 dynamic linker
* Backport of [AArch64] Correct signedness of builtins, remove casts from
arm_neon.h
* Backport of [AArch64] clarify stack layout diagram
* Backport of [AArch64] Implement movmem for the benefit of inline memcpy
* Backport of [AArch64] Fix REG_CFA_RESTORE mode.
* Backport of [AArch64] Fix layout of frame layout code.
* Backport of [AArch64] Fix some reg-to-reg move scheduler types.
* Backport of [AArch64] Implement CRC32 ACLE intrinsics + testsuite.
* Backport of [AArch64] Implement ADD in vector registers for 32-bit scalar
values.
* Backport of [AArch32/AArch64] TARGET_ATOMIC_ASSIGN_EXPAND_FENV AArch64
* Backport of [AArch32/AArch64] Use signed chars in gcc.dg/pr60114.c.
* Backport of [AArch32/AArch64] Rewrite UZP Intrinsics.
* Backport of [AArch32/AArch64] Rewrite TRN Intrinsics.
* Backport of [AArch32/AArch64] Rewrite EXT Intrinsics.
* Backport of [genattrtab] Fix memory corruption, allocate enough memory for all
bypassed reservations
* Backport of Fix PR c/60114

[1] Stable source package releases are defined as releases where the full Linaro
Toolchain validation plan is executed.
[2] Engineering source package releases are defined as releases where the
compiler is only put through unit-testing and full validation is not
performed.
=Progress=
GNU Cauldron
TCWG Sprint [8/10]
* Really helpful to meet (almost) everybody
* Some useful discussion, too
memcpy on A15 - TCWG-390 [1/10]
* Should have let this lie but I had an odd 1/2 day and some data
begging to be looked at
* Turned out I'd fat-fingered the wrong data
* But I gained more evidence suggesting that cortex-strings
benchmark is too noisy
(Non-sprint) meetings/mail etc [1/10]
=Plan=
cbuild2 benchmarking
* Fit what I have into Rob's worldview
* Hopefully convert it into some reviewable patches

Hi all concerned:
this test code I given below: AARCH32
[https://email-cn04.huawei.com/owa/14.3.158.1/themes/base/pgrs-sm.gif]
Test function[X][X]
{
volatile unsigned int val0 = 0;
volatile unsigned int val1 = 0;
asm volatile(“mrrc p15, 1, %0, %1, c15” : “=r”(val0), “=r”(val1))
val0 &= ~(1<<6);
val1 &= ~(1<<6);
asm volatile(“mcrr p15, 1, %0, %1, c15” : “=r”(val0), “=r”(val1));
}
After compiling, the result is:
mrrc 15, 1, r2, r3, cr15
str r2, [fp, #-28]
str r3, [fp, #-24]
ldr r3, [fp, #-28]
bic r3, r3, #64;
str r3, [fp, #-28]
ldr r3, [fp, #-24]
bic r3, r3, #64
str r3, [fp, #-24]
mcrr 15, 1, r2, r3, cr15
obviously , it is not what I expect. I have val0 an vl1 two vars, but the compiling result is only one val takes effect.
especia I have to mention is AARCH32.
thanks.
Peter
