i#3544 RISC-V, part 5: Add atomic functions

5

Add RISC-V implementation of most atomic functions. Several are left unimplemented (the exchange variants), only containing a non-atomic logic as a reminder of what the given function should do. Issue:...

i#3544 RISC-V, part 8: Add core/ir stubs

4

Add stubs to get the IR related code to compile. Most of the code is non-functional, with exception of the register name list. Issue: #3544 Signed-off-by: Stanislaw Kardach

i#3544 RISC-V, part 6: Add extension stubs

4

Add definitions required for extensions to compile for RISC-V. NOTE: This code is not validated and mostly contains stubs as the main point was to achieve compilation and estimate the...

AArch64: `dr_get_mcontext()` and `dr_set_mcontext()` do not handle `fpcr` and `fpsr` registers.

As discussed in a [RISC-V related pull request](https://github.com/DynamoRIO/dynamorio/pull/5588#discussion_r938212368), none of the `dr_mcontext_flags_t` flags cause the floating point control and status registers to be saved/restored. I have a similar case where...

RISC-V does not have condition codes. Instead all conditional branches are arithmetic register comparison based and those are also used for overflow checking. Therefore remove the xflags field so that...

I went to check that we generate all fields for all architectures for dr_mcontext_t and found that only size and flags are listed: https://dynamorio.org/struct__dr__mcontext__t.html
