5 daystarget/loongarch: Use explicit little-endian LD/ST APIPhilippe Mathieu-Daudé1-4/+4

2023-08-24target/loongarch: Split fcc register to fcc0-7 in gdbstubJiajie Chen1-9/+7
Since GDB 13.1(GDB commit ea3352172), GDB LoongArch changed to use fcc0-7 instead of fcc register. This commit partially reverts commit 2f149c759 (`target/loongarch: Update gdb_set_fpu() and gdb_get_fpu()`) to match the behavior of GDB. Note that it is a breaking change for GDB 13.0 or earlier, but it is also required for GDB 13.1 or later to work.

2023-03-07gdbstub: move register helpers into standalone includeAlex Bennée1-0/+1
These inline helpers are all used by target specific code so move them out of the general header so we don't needlessly pollute the rest of the API with target specific stuff. Note we have to include cpu.h in semihosting as it was relying on a side effect before.
