...ot, as it finds it all by itself. And the winner is.. clang++ -ccc-gcc-name arm-none-linux-gnueabi-g++ -ccc-host-triple thumbv7m-none-gnueabi testReference.cpp -c It seems like it worked. $ arm-none-linux-gnueabi-objdump -D --section=.text testReference.o testReference.o: file format elf32-littlearm Disassembly of section .text: 00000000 <main>: 0: e92d4800 push {fp, lr} 4: e1a0b00d mov fp, sp 8: e24dd030 sub sp, sp, #48 ; 0x30 ... I'm not 100% sure if that's the correct ISA, because I haven't run the code, but it seems ok. I of course own you a beer :-) Than...

Hi, MIPS LA25 thunk is used to call PIC function from non-PIC code. Usually it contains three instructions: lui $25, %hi(func) addiu $25, $25, %lo(func) j func We can write such thunk in an arbitrary place of the generated file. But if a PIC function requires the thunk is the first routine in a section, we can optimize the code and escape jump instruction. To do so we just write the
