digitalmars.D.ldc - Current ABI differences between DMD and LDC

reply solidstate1991 <laszloszeremi outlook.com> writes:
I'm planning to write a few functions purely in x86 Assembly 
(later adding ARM and other platforms), and I'm planning to 
support both DMD and LDC. As I'm running into massive issues when 
compiling and running very long assembly codes in LDC (see this: 
https://github.com/ZILtoid1991/CPUblit/blob/master/src/CPUblit/composing.d), I
came up with the solution of using an external assembler like NASM, then add
its build commands to DUB's prebuild commands. Should I go with C or D API for
function calls? Or issue a D improvement proposal on fixing the SIMD support?

As far as weird corner cases go, this doesn't really qualify as "very 
long" yet – perhaps we could fix these issues?

It looks like a single issue, potentially trivially to fix. I 
already told him to create a new issue with reduced testcase:

Yep – I created this:
