Does MinGW cross-compile IA64?

Question

I want to cross-compile Windows IA64 binaries in Linux platform.

Can MinGW be ported to do it?

Answer 1

No. MinGW produces 32-bit executables only. MinGW-w64 supports 32 and 64-bit x86 binaries but not IA64

Features

• ...
• Supports 32-bit and 64-bit Windows i386/x64
• Supports Multilib toolchains
• Supports bleeding edge gcc/binutils

There was a request to support Windows IA64 in GCC long time ago but I doubt it anyone would spend time supporting that architecture. Even Microsoft abandoned Itanium for years.

To the Team of GCC,
Our Developing Team is looking for a 64-bit Compiler that would be able to Compiler 64-Bit Windows Applications for the IA-64 Architecture and possibly the x86-64 bit Architecture.
I am Inquiring as to whether a IA-64 Windows Platform Version of GCC has yet been procured or if not when in the future a version might come across.

There is no IA-64 windows support in gcc at this time.
It will be available if and when someone contributes the code to the FSF. It is not possible to predict if or when this will happen.

Forking mingw to support IA64 might be possible but would take a lot of effort. I think the easiest way is using LLVM because only a backend for translating IR to IA64 instructions is needed
