Hi!
If simdlen clause is specified, it is the preferred number of concurrent
simd lanes in the loop, though if if clause is specified and evaluates to
false, the preferred number of simd lanes is 1 (i.e. no vectorization).
This patch handles just the easy part, when simdlen argument is 1 or when

Without this, when we are unwinding across a signal frame we can jump
to an even address which leads to an exception.
This is needed in __gnu_persnality_sigframe_fdpic() when restoring the
PC from the signal frame since the PC saved by the kernel has the LSB
bit set to zero.

The main difference with existing support is that function addresses
are function descriptor addresses instead. This means that all code
dealing with function pointers now has to cope with function
descriptors instead.
For the same reason, Linux kernel helpers can no longer be called by

In FDPIC, we need to make sure __do_global_dtors_aux and frame_dummy

In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie,
-fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code
for executables rather than shared libraries by default.
We also make sure to use the --fdpic assembler option, and select the
appropriate linker emulation.
The FDPIC register is hard-coded to r9, as defined in the ABI.
We have to disable tailcall optimizations if we don't know if the
target function is in the same module. If not, we have to set r9 to
the value associated with the target module.
When generating a symbol address, we have to take into

Hello,
This patch series implements the GCC contribution of the FDPIC ABI for
ARM targets.
This ABI enables to run Linux on ARM MMU-less cores and supports
shared libraries to reduce the memory footprint.
Without MMU, text and data segments relative distances are different

I somehow missed this testsuite failure...
Attached patch is needed. I'll commit it later today.

Hi!
If we build Darwin with a modern assembler, then it might well
recognise insns that cannot be used on current Darwin systems.
The patch augments the tests for feature support for VSX,
power8 and power9 to exclude Darwin even if the assembler can
handle the instructions.

Just a general comment about this part. Wouldn't it make sense to use regex
