Hello, I am currently facing an issue at linking stage when compiling basic C code for an embedded PPC32 platform and linking with LLD. For external symbol linkage LLVM appears to use PLT which results in generating a R_PPC_PLTREL24 relocation, that is not support by LDD. Therefore even such a basic example cannot be built: /* s.c */ int f() { return 0; } /* t.c */ int f(); int _start() { return f()...

Hal, I very well understand that LDD may not be in a good state for PPC32, and it would definitely need some improvements sooner or later. In fact I even submitted a patch adding a relocation to ldd just a few hours ago. However, this particular case is not related to LDD, it is a design issue and furthermore a regression in LLVM itself. I checked gcc, and neither does...

Hello ppc32 users, I think I finally got the "official" answer on the ppc32 problem. Apparently some distributions build binutils so that it defaults to elf32ppc emulation rather than elf32ppclinux. This doesn't matter when using gcc, since gcc overrides the emulation explicitly, but it doe...

A while back, there was mention that the release of CentOS 4.3 would bring a ppc32 version. Is this still in the works? If so, is it scheduled to be released at the same time as the more popular releases, or at a later time? Thanks, Barry

Does anyone have any news about the PPC32 release of CentOS 4? Thanks, Barry

Can anyone tell me how the ppc32 version of CentOS-4 is coming along? Thanks, Barry

Hi For .LL like: define void @Func() { %var1 = alloca double store double 0x40bb580000000000, double* %var1 ret void } ppc32 output is: ... lis 3, 16571 ori 3, 3, 22528 li 4, 0 stw 3, 8(1) stw 4, 12(1) ... I'm using the PPC backend's output as the "bytecode" for an interpreter that I would like to be able to run on both little- and big-endian platforms. The split stw's...

Hi! I am trying to implement va_arg() on ppc32. Everything went smooth, except implementing va_arg() of 64bit int. Since i64 is not a legal type on ppc32 DAGTypeLegalizer::ExpandRes_VAARG() splits the va_arg(i64) into two i32 va_args. The problem with ppc32 va_arg is that it needs special "alignment" of its gpr pointer when the argu...

Hi, I am wondering why we dont support PPC32 LE? Here is the output of llvm-mc --version, in which only PPC32, PPC64 & PPC64LE are supported. $ llvm-mc --version LLVM (http://llvm.org/): LLVM version 3.6.2 Optimized build with assertions. Built Aug 2 2015 (11:39:46). Default target: x86_64-apple-darwin15.4.0 Host CPU: core-a...

...omewhere - clang defaults to 64bit assembly (if I understood the output correctly), and the assembly made from running 'clang --ccc-host-triple=powerpc-linux-gnu' is not accepted by the default system assembler. It might work better on a 64bit system. And I probably should file a bug. Is ppc32 still maintained? kalle -- "Modern computing machines are very complex objects" -von Neumann introducing the NORC, 1954

Does anyone have CentOS 4 running on an iMac? Any caveats or useful tips? Where are the ISOs located these days? TIA, Barry

The _start stuff was changed some time ago, but ppc was not updated. This fixes klibc for me. I'm not sure what to do with the second arg to __libc_init, so I set it to 0.. However, looking at other static binaries, there is more stuff todo. diff -p -purNx linux -x '.*.d' -x syscalls -x socketcalls y/klibc-0.87/klibc/arch/ppc/crt0.S klibc-0.87/klibc/arch/ppc/crt0.S ---
