Hello, I have tried to port tinycc to my PXA270 based PDA running WM6, but with little success.
1) gcc -D TCC_TARGET_ARM -D TCC_TARGET_PE seems to somewhat work, and the resulting (x86 ELF) TCC emits ARM code and links PEs. I don't know what the FPA/LD/VFP/EABI flavors mean and what they're good for, so I just used ARM-TCC-FPA, which seems to be the default(?) one (no additional -Ds used in Makefile). 2) now I try to self-compile this beast to get native version of the same compiler. There's a problem with get_caller_pc (which can be ignored), and with libtcc1.c (i used precompiled libtcc.a from http://www.stud.uni-hannover.de/~daniel/tcc/). Still, there are undefined symbols __floatundidf (i took one from libtcc1.c) and __floatdidf (wtf is this?, I'v patched arm-gen.c, so only the unsigned version is ever used). Now everything is resolved, but it still can't link. 3) I get "can't relocate value" messages. These come from type=1 (R_ARM_PC24) relocations which are on invalid offsets. They are in fact R_386_32 relocations created by pe_check_symbols() at tccpe.c:1136. This code adds indirect jumps via IAT and is clearly i386-only, and that's where the invalid "offset + 2" came from. I know a little about PE, but almost nothing about ARM, so it's a showstopper. Q: Is it possible to fix tccpe.c so it supports ARM target? What else needs to be fixed? Any resources? Thanks! -- Zdenek Pavlas GTS Novera a.s.
