-mflip-thumb. Switch ARM/Thumb modes on alternating functions. This option is provided for regression testing of mixed Thumb/ARM code generation, and is not intended for ordinary use in compiling code. -mtpcs-frame. Generate a stack frame that is compliant with the Thumb Procedure Call Standard for all non-leaf functions. Sep 13, 2016 · I know they somehow compile for Thumb-only target with the same build system (perhaps configuring in a different way, different target, options etc), but I can't reproduce so far the problem where my ARM assembly fails to compile on a Thumb-only CPU. I've looked through gcc options for Thumb and got only the above ideas.
Jul 10, 2018 · For gas you need to put.thumb_func before a label that you want declared as a thumb label (the term func implying function is misleading, dont worry about what.thumb_func means it just is an assembler/linker game)..thumb.thumb_func ping: ldr r0,=pong bx r0.code 32 pong: ldr r0,=ping bx r0 and now we get what we wanted. In this situation, it usually makes sense to compile Thumb code and hand-optimise a few of the most CPU-intensive sections using full 32-bit ARM instructions, placing these wider instructions into the 32-bit bus accessible memory. The first processor with a Thumb instruction decoder was the ARM7TDMI. All ARM9 and later families, including Bits: 32-bit, 64-bit.
Apr 22, 2011 · ARM claims that Thumb-2 instructions (for ARM Cortex cores and all ARMv7 processors) provides performance improvements and code size optimization: Thumb-2 - No Comments on Compile with ARM Thumb2 to Reduce Memory Footprint and Improve Performance.

The Thumb instruction set The Thumb instruction set is a subset of the most commonly used 32-bit ARM instructions. Thumb instructions are each 16 bits long, and have a corresponding 32-bit ARM instruction that has the same effect on the processor model. Thumb instructions operate with the s.
