Dear Sir,
Thanks for you page. it is really very helpful to us.
We are facing a problem during compiling GCC for our ARMv7-a Cortex-a9.
We are using following option:
1.
../gcc-linaro*/configure --disable-bootstrap --enable-languages=c,c++
--with-mode=thumb --with-arch=armv7-a --with-tune=cortex-a9
--with-float=hard --with-fpu=vpfv3-d16 --prefix=$home/gcc/gcc-linaro
2.
make -j`getconf _NPROCESSORS_ONLN`
after 2 step we are getting following error:
checking whether putc_unlocked is declared... yes
checking whether getrlimit is declared... yes
checking whether setrlimit is declared... yes
checking whether getrusage is declared... yes
checking whether ldgetname is declared... no
checking whether times is declared... yes
checking whether sigaltstack is declared... yes
checking whether madvise is declared... yes
checking for struct tms... yes
checking for clock_t... yes
checking for F_SETLKW... yes
checking if mkdir takes one argument... no
Unknown CPU given in --with-arch=armv7-a.
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory `/home/anwej/src/build'
make: *** [all] Error 2
Please suggest the solution. where is the problem and what will be our next
steps.
Thanks in advance.

Hi,
The preprocessed file:
http://people.linaro.org/~rikuvoipio/qmltextgenerator.ii.gz
With compile command line:
g++ -save-temps -c -g -O2 -fstack-protector --param=ssp-buffer-size=4
-Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fvisibility=hidden
-fvisibility-inlines-hidden -Wall -W -D_REENTRANT -fPIC -o x.o
qmltextgenerator.ii
Will take apparently forever (north of 1600min) on a debian native gcc. -O
compiles instantly. Some bisecting for gcc optimization flags later,
disabling strict aliasing allows instant build as well:
g++ -save-temps -c -g -O2 -fno-strict-aliasing -fstack-protector
--param=ssp-buffer-size=4 -Wformat -Werror=format-security
-D_FORTIFY_SOURCE=2 -fvisibility=hidden -fvisibility-inlines-hidden -Wall
-W -D_REENTRANT -fPIC -o x.o qmltextgenerator.ii
Happens with:
gcc version 4.8.2 (Debian 4.8.2-19)
and
gcc version 4.9.0 20140405 (experimental) [trunk revision 209146] (Debian
20140405-1)
Linaro binary cross-compilers are compile the file fine with -O2.
do we do native gcc testing, or should it be just submitted upstream
bugzilla?

The Linaro Toolchain Working Group is pleased to announce the 2014.04
release of both Linaro GCC 4.8 and Linaro GCC 4.7.
As announced at Linaro Connect USA 2013 Linaro GCC moved to a pattern of
quarterly stable releases, with engineering releases in the intervening
months. This is the second stable release, and contains no known regressions
compared to the 2014.01 release.
The next stable release of GCC 4.8 will be the 2014.08 release. There will be
no engineering releases of GCC 4.8 until this release, as it enters in
maintenance.
No more releases of GCC 4.7 are planned.
Next month's release - 2014.05 - will be based off GCC 4.9 and be an
engineering build.
Linaro GCC 4.8 2014.04 is the thirteenth and last development release in the
4.8 series before entering maintenance. Based off the latest GCC 4.8.3+svn208968
release, it includes performance improvements and bug fixes.
Interesting changes include:
* Updates to GCC 4.8.3+svn208968
* Cortex-a53 support
* A fix for LP #1292489: Buggy vectorization of dot products
* A fix for LP #1268893: ICE when building kernel raid6 neon code
* A fix for LP #1273511: ICE APCS Frame & optimize-sibling-calls
Linaro GCC 4.7 2014.04 is the twenty third release in the 4.7 series. Based
off the latest GCC 4.7.4+svn209005 release, this is the tenth release after
entering maintenance and the final one.
Interesting changes include:
* Updates to GCC 4.7.4+svn209005
* A fix for LP #1129013: Internal compiler error in push_reload during
bootstrap stage 2
* A fix for LP #1292489: Buggy vectorization of dot products
* A fix for LP #1301335: Compiler segmentation fault while cross-compiling QT5

I compiled my code with debug symbols on an BeagleBoneBlack using Debian
gcc-4.7. If I use objdump -S on my object file, I see both source lines
and disassembly. On my Ubuntu 13.10 host, using
gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux, I do
arm-linux-gnueabihf-objdump -S on the same object file, I see disassembly
lines, but the source lines are not displayed. I¹m attempting to debug my
code with a Lauterbach JTAG debugger, but no source code is available
which makes debugging very difficult.
Is there some compatibility issue here or am I doing something wrong?
Regards,
John
== Progress ==

-- Support to run native and native-gdbserver test via ssh on remote
machines like arm-linux.
-- Bug fix and test gdb testing utility by running it various configurations.
-- Update wiki page with testing utility and how to use it.
* Chromebook ubuntu re-install and fix network lag issue [2/10]

-- Start implementation of reverse debugging infrastructure [TCWG-398]
-- Add support for running aarch64 gdb test suite in gdb testing utility.
== This week ==

- aarch64-none-elf target using cpu=cortex-a53 passed validation on
foundation model
- Resolved code review issues (formatting and unnecessary patches)
Backport 202663 - vectorizer bug passed validation and merge review for
4.7 and 4.8 [CARD-300][3/10]
GCC Bugzilla bug 60657 [TCWG-290][2/10]

== Future ==
One week of vacation either the third or fourth week of April.
=== Progress ===
LP1296601 (ICE in push_minipool_fix) [5/10]
* completed a prototype fix
* submitted RFC patch to gcc-patches
* still awaiting review
PR60609 (Error: value of 256 too large for field of 1 bytes) [3/10]
* implemented fix and posted to gcc-patches
* approved, subject to further testing on Thumb-1
libvpx NEON assembler vs instrinsics performance investigation [2/10]
* looking at disassembly, code is not terribly aesthetically pleasing
* in some cases clang looks better
=== Plan ===
write up libvpx investigation
follow up/ping LP1296601
NEON scheduling TCWG-135
TCWG-156 (5/10)
* Hacked v7 memcpy into a memset
* Much fiddling with builds, targets
* Kicked off a benchmark run
Misc
* Meetings (1/10)
* Finding hardware/setting up working environments/figuring out workflows
(4/10)
== Issues ==
* none
== Progress ==

- re-spawned some jobs.
* Backports review: (5/10)
o cortex-a53 support backport:
- We are still not able to validate it on aarch64-linux-gnu target
