The test suite is now a developed in a separate git repository.
See here:
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git
The test suite should be just like every other software compiled
with the cross-toolchain. In the past strange problems where found
when the test suite got build in the toolchain creation step.

Somehow this got removed with f1d7505e40654a185843bdc8f1cf1fd00ab55c04.

This is because some old ARC750 cores lack these instructions.
We now rely on the default for the toolchain driver:
-mcpu=A7 won't enable those, while -mcpu=archs will as these
instructions are baseline (and thus is not impacted with this change).
If some arc700 based cpu does have them, it can override the driver
defaults in it's one level up build system.

To analyze or debug any linuxthreads problems it is useful to
have the ability to have a full gdb on the target available.
At the moment you could only debug stuff on microblaze.
Now we can verify that linuxthreads are working fine for
every supported architecture.

There was a deadlock hanging in a sycall to futex,
which should be solved now.

Despite the prev fix, tst-mqueue3 was still segfaulting.
The issue was BLINK register not restored properly for return

26fa: cmp r0,-1024 |
26fe: jls [blink] -----|
2702: b 15d8

So the fix was to retain BLINK on stack before function call, and pop it
later
- 26d8: ld.ab blink,[sp, 4]
+ 26d8: ld blink,[sp] <--- restore BLINK, but retain on stack
26dc: mov r8,182
26e0: trap_s 0
26e2: cmp r0,-1024
26e6: st.aw r0,[sp,-4]
26ea: mov r0,r9
26ee: bl 1e90 <__librt_disable_asynccancel>
26f2: ld.ab r0,[sp,4]
+ 26f6: ld.ab blink,[sp,4] <--- finally pop BLINK
26fa: cmp r0,-1024

This was reported as uClibc test suite failures of tst-mqueue3 and
tst-mqueue5.
The syscall args were getting clobbered, so use scratch regs which are
not used for syscall args

Fixes compilation of uClibc-ng when UCLIBC_HAS_LONG_DOUBLE_MATH is
used.

The nested libpthread_nonshared.a and libdl.os shouldn't be included
in the static libc.a. Fixes compile issues for static builds.
|
|
The tests shouldn't include libgcc exception handling functions directly
from libgcc.a when a non-shared gcc compiler is used while compiling
the testcases. These fixes open testsuite regressions found for
ppc and xtensa.

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.
- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
-lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

Seems better and more stable.

We do not support 2.4 Linux kernels anyway, and almost
all newer 2.6 kernels should have tgkill syscall.
Cleanup the raise situation, pt-raise.c is unused, sync
raise.c with latest GNU libc.

The time to run the tests is very high and always subtests
are failing. We need to fix the subtests and see how to reduce
the time the test is running. At the moment it blocks
my regression testing to much.

elf-fdpic.h or elf-dsbt.h is included by link.h. When C++ program
includes <link.h>, we get following build failure.
../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)':
../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void'
void pointer addition and subtraction is not allowed in C++ as it has
undetermined size, however in C with language extension it is possible
because sizeof void is treated as one byte.
Instead of performing subtraction on void pointers, typecast it to char*
first.
This build failure is detected by Buildroot autobuilder.

A single test with targeting ARM showed that this feature
seems bit rotted. Remove DOMULTI and simplify Makefiles.

Max ULP for "cos (M_PI_6l * 2.0) == 0.5" in "test-double" sub-test
is set to "0" for ARC. It causes "test-double" test failure.
I realized that this sub-test on ARM gets completely same results.
But it doesn't fails on ARM because max ULP is set to "1" for ARM.
I am wondering, if it was done for any special reason?
Otherwise, set max ULP for "cos (M_PI_6l * 2.0) == 0.5" test to
"1" instead of "0" for ARC.

Add -Wdeclaration-after-statement when EXTRA_WARNINGS is enabled.

The syscall ABI includes the gcc functional calling ABI since a syscall
implies userland caller and kernel callee.
The current gcc ABI (v3) for ARCv2 ISA required 64-bit data be passed in
even-odd register pairs, (potentially punching reg holes when passing such
values as args). This was partly driven by the fact that the double-word
LDD/STD instructions in ARCv2 expect the register alignment and thus gcc
forcing this avoids extra MOV at the cost of a few unused register (which we
have plenty anyways).
This however was rejected as part of upstreaming gcc port to HS. So the new
ABI v4 doesn't enforce the even-odd reg restriction.
Do note that for ARCompact ISA builds v3 and v4 are practically the same in
terms of gcc code generation.
This change is dormant for now (gcc 4.8.x based tools) and will only kick
in with switch to gcc 6.x based tools.

Fix a regression introduced by commit
0550ecce0e6580c5ad34e9a9a39ff18ccf8774f9
Reported by Buildroot developers.
Embedded test must be extented to ARMv7 thumb2 builds to
find such regressions next time. It wasn't triggered by a
cortex-m4 ARM noMMU build.

CVE-2016-4429:
The call is technically in a loop, and under certain circumstances
(which are quite difficult to reproduce in a test case), alloca
can be invoked repeatedly during a single call to clntudp_call.
As a result, the available stack space can be exhausted (even
though individual alloca sizes are bounded implicitly by what
can fit into a UDP packet, as a side effect of the earlier
successful send operation).
