things make taking advantage of it somewhere between hard and

Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.

https://reviews.llvm.org/rL298380, however few instruction options were missing.
This change adds negative immediates support and respective tests
for the following:
ADD
ADDS
ADDS.W
AND.W
ANDS
BIC.W
BICS
BICS.W
SUB
SUBS

* clang-tools-extra/docs/Doxyfile seems to be unused and irrelevant,

This patch adds <isl_space.h> to gpu_tree.c. This prevents a segfault

the compiler now knows that the return type is a pointer instead of
