Hi!
The testcase in the PR doesn't hoist any memory loads from the large
switch
before the switch on aarch64 and arm (unlike e.g. x86), because the
arm/aarch64 casesi patterns don't properly annotate the memory load from
the
jump table. It is created by gen_* and in RTL directly one can't specify
the needed flags (MEM_READONLY_P and MEM_NOTRAP_P).
Fixed thusly, bootstrapped/regtested on armv7hl-linux-gnueabi and
aarch64-linux, ok for trunk?
Since you're changing Arm and Thumb-2-specific paths can you please make
sure to bootstrap configurations --with-mode=arm and --with-mode=thumb.
The only bootstraps I'm doing are distro builds with
--with-tune=generic-armv7-a --with-arch=armv7-a \
--with-float=hard --with-fpu=vfpv3-d16 --with-abi=aapcs-linux
I don't have setup nor experience with configuring anything else, don't
really know what is and what isn't ABI compatible etc.
Isn't --with-mode=arm the default with the above set of options? Can
--with-mode=thumb be used ABI compatibly with that, or is that incompatible?
They are ABI-compatible. Running the testsuite with -mthumb in
RUNTESTFLAGS would also be enough in this case if you don't have the
cycles for a bootstrap.
Thanks,
