Is there a place I can learn LLD inline assembly with GCC syntax?

[rempas]

I want to learn how to use inline assembly for LDC with GCC 
syntax specifically so I can support all the targets (as 
[here](https://wiki.dlang.org/Compilers) it is said that DMD 
intel-like syntax only supports the "i386" and "amd64" targets) 
but I cannot find anything other 
[this](https://wiki.dlang.org/LDC_inline_assembly_expressions) 
outdated page where It seems that it doesn't work (at least not 
for the sys_write example). Any ideas?
