Hello Tristan I think the main issue is that EFI C dialect is not ANSI-C compliant: the size of pointer is determined at the run-time and therefore the layout of the structure is not static. Gcc doesn't support this model. I have read the sizeof and VLA in C99 I found a example: EXAMPLE 3

Hello Tristan, I think the main issue is that EFI C dialect is not ANSI-C compliant: the size of pointer is determined at the run-time and therefore the layout of the structure is not static. Gcc doesn't support this model. As I read some related information, LLVM IR doesn't care the size

Hello Andrew, Who would maintain this EFI back-end? The EFI specification was originally developed by Intel, and is now managed by the Unified EFI Forum[http://www.uefi.org/home/]. So, you don't know who would maintain the EFI back-end that you're proposing for gcc? I feel sorry that I mis

Hello Joe, The other hurdle would be the ABI. It's very particular since it has to accommodate calling into and from EBC, x86, x86_64, ia64, and any other architecture available. It's structured mainly on Microsoft's stdcall ABI. I have read the part about EBC of EFI specification.But I foun

Hello. I'm actually an EFI engineer so this project is of great interest to me. I would be willing to lend a hand off hours if this goes through, so please keep me in the loop. I think the biggest hurdle would be the c front end since EBC (EFI byte code) introduces variable sized pointers as wel

引述 Andrew Haley : There is no reason in principle this shouldn't be part of gcc. I think no-one has responded yet because they don't know what it would be for, and how much work it would involve. What compiler doing is: c -> intermediate language -> asm(ex. x86). And then, c compiler for efi
