Owen, Nick, et. al., I've been working towards the same objective and stumbled across your post. I tried Nick's fix of 4/21 and had similar results. I believe that there is an additional problem. If you go to the HOWTO() macro for R_ARM_THM_PC8 (elf32-arm.c, line 235), it shows a shift count of one. ARM's documentation shows that the R_ARM_THM_PC8 relocation is only used for an LDR(3) instruction, which uses a shift count of two: Syntax LDR <Rd>, [PC, #<immed_8> * 4] where: <Rd> Is the destination register for the word loaded from memory. PC Is the program counter. Its value is used to calculate the memory address. Bit 1 of the PC value is forced to zero for the purpose of this calculation, so the address is always word-aligned. <immed_8> Is an 8-bit value that is multiplied by 4 and added to the value of the PC to form the memory address. I haven't had a chance to rebuild and test it with a shift count of two. I don't subscribe to the mailing list, but if you are interested in how it comes out, email me at jays at spectralogic dot com and I will let you know. I'd ask that you do the same if you find anything out. Thanks for the suggestions so far, and good luck.
