I would expect a good CRC benchmark to print CRC throughput in
bytes per cycle or megabytes per second.
I don't see where Coremark states that goal. In the readme at
https://github.com/eem
This is a request for feedback and a proof-of-concept, not something I
intend to merge as-is. It would be nice if gcc, maybe just under some
circumstances, always generated an else-block for coverage purposes.
I am working on the MC/DC support by CFG analysis for a while

The issue here is that when backprop tries to go
and strip sign ops, it skips over ABSU_EXPR but
ABSU_EXPR not only does an ABS, it also changes the
type to unsigned.
Since strip_sign_op_1 is only supposed to strip off
sign changing operands and not ones that change types,
removing ABSU_EXPR here i
This patch adds the LoongArch64 support for GCC D frontend.
The runtime support is submitted as a separate patch here:

* config.gcc: add loongarch-d.o to d_target_objs for LoongArch
architecture.

(loongarch_d_target_versions): add interface function to define builtin
D versions for LoongArch architecture.

Hi,
This patch implements 32bit inline lrint by "fctiw". It depends on
the patch1 to do SImode move from FP registers on P7.
Compared to last version, the main change is to add some test cases.

Bootstrapped and tested on p
