The function is here: https://github.com/DynamoRIO/dynamorio/blob/95fd0237a5b9c9ca1add88574f9bddca002a82e9/core/unix/os.c#L2507-L2538 If you ask for `num_slots > 1` then the implementation wants every slot to be aligned, which fails if the `alignment` is greater than the...

Minor changes to permit building with older toolchains.

Make some code conditional on EM_RISCV or PR_SVE_GET_VL being defined. This was needed on RHE7, which will be around for a few more years. We also check for another older...

AArch64 vector instructions: use size field of register opnd instead of immediate integer

1

Currently the AArch64 codec uses an immediate integer operand to indicate the size of the elements operated on by a v8.0 vector instruction, for example (see `dis-a64.txt`): ``` 0e228420 :...

AArch64 codec imm5 encodes width and position of vector element

2

It is currently (568aef530228d197ff2fed5f13409e1511addee3) impossible to encode `5e020400 mov h0, v0.h[0]` (which is an alias of DUP): you get `4e020400 dup v0.8h, v0.h[0]` instead. Demonstrate by adding this line to...

See #6420 and #431.

I spent a long time wondering why the following (trying to get a `UMOV , .[]`) didn't work: ``` instr_create_1dst_3src(drcontext, OP_umov, opnd_create_reg(wreg), opnd_create_reg(qreg), opnd_create_immed_int(0, OPSZ_1), opnd_create_immed_int(2, OPSZ_1)); ``` The helpful...

The tests in `ir_aarch64.c` that require extensions such as FP16 should presumably be moved to other files such as `ir_aarch64_v82.c`. This isn't just for tidyness: `code_api|api.ir` currently fails on hardware...

This line seems to make all variants of FCVTZU (vector, fixed-point) require FP16: https://github.com/DynamoRIO/dynamorio/blob/0192e25ec92c7540f4179727e23b3ebd72c0f4db/core/ir/aarch64/codec_v82.txt#L118 But in fact only the variants that match `0x1011110001xxxx111111xxxxxxxxxx` require FP16, as I understand it. The...

Glitch in interrupt handling? Missed interrupt?

Test program Cargo.toml: ``` [package] name = "testtcp" version = "0.1.0" edition = "2021" [dependencies] [target.'cfg(target_os = "hermit")'.dependencies.hermit] path = "../rusty-hermit/hermit" ``` Test program src/main.rs: ``` #[cfg(target_os = "hermit")] use...

Make communication between Veracruz client and runtime manager simpler and faster.

The current code seems to be more complex than necessary, for historical reasons, and appears to perform poorly, particularly in terms of latency. Issue #378 has helped a lot, but...
