Are you targeting ARM32 ARM64 or ARM64 EC?
Could you get me a login to a VM with the right OS and the right CPU and a step
debugger? email me direct or leave your email
single Doubles/floats params, in reg, and then stack spill over are drama.
128 bit integers are drama (secret &i128var pointer or split between 2 64b
regs?)
reading some docs, integer types and C structs upto 16byte are x0/x1 retval
split, FPs are v0-v32 128bit with v0-v3 used to return a single FP or SMID
vector types. C structs over 16 bytes are return by memory, I/nobody didn't
implement that in Win32::API.
Basically getting char/short/U32/U64 params, and float/double/fp128 params
right, and return types right is priority 1. variodic and pass by copy C
structs are priority 2. SIMD variables like __m128 and XMMs (vectors/machine
type array of same size scalars) are priority 3.
I'd really need VM access to work on this solo since I dont own any Win ARM
machines.
There might be other things like "Callguard" or "Super Secure Structured Stack
Exception Handling Platinum Plus With SecureGuard Gold" in Win 8/10/11 that
needs to be bypassed since someone reported VC 2022 on x86-32 crashes during
unit testing but gave no other details.
