I can't see how this would be integrated into the existing IRGen infrastructure in clang with...

Hello all, I want to the do followings: (1) Modify the LLVM front-end(clang) to support EFI C (2) Add EFI Byte Code target to LLVM I am wondering to know which task should I do first, modify front end or porting LLVM? thanks yi-hong -------------- next part -------------- An HTML attachment was scrubbed...

A piece of EBC code can run in either a 32 bit or 64 bit environment, and everything in the compiler either needs to cope with it (by conditionally choosing the size of offsets into structs, for instance) or give up on it and abort. Th...

You might want to look at the challenges discussed in this thread, mainly that pointer size

...trating time getting multiple parking lots to work and am wondering what I am doing wrong. I am using Asterisk 1.6.1.1. I defined two separate parking lots in features.conf as follows: [parkinglot_a100] ; SSI context => a100-parking parkpos => 900-920 findslot => next [parkinglot_a10] ; EBC context => a10-parking parkpos => 800-820 findslot => next I then set the parkinglot parameters in sip.conf as follows: [general] context=incoming tos_audio=0xb0 tos_sip=0xb0 disallow=all allow=ulaw allow=alaw allow=speex allow=gsm canreinvite=nonat [common](!) type=friend host=dynamic...

In my opinion, if the EBC VM is running on 32-bit processor, return value is 4 if the EBC VM is running on 64-bit processor, return value is 8 If error out on any sizeof that include a pointer, does it means that no issue about pointer size determined at runtime?? > It doesn't, at least not for Intel's EBC com...

This is something we specifically do not want to support. The issue is not the parser, the issue is that struct field offsets are no longer constant in

What is it? EFI describe structures almost like C. There are EBC instructions that have two immediates: one for 32bits pointers and one for 64bits pointers.

Hello Chris, Which won't matter (as long as sizeof is consistent), because EFI is a > closed system. > What is the meaning of closed system?? Is it 1. not open source 2. EBC binary is only running on a single EFI EBC interpreter and never interfacing with the outside VM?? thanks ching -------------- next part -------------- An HTML attachment was scrubbed...
