Sorry, I cannot think of a way to do this. Compiling the reset handler separately with GCC is indeed the only solution I can think of.

However adding support for just this assembly mnemonic might not be much work and might encourage other people to add some more later. Would you like to give it a try? I can provide some help in what would need to be done.

Best regards,

I don't know if my request is related to the original one.
In a MCU firmware, the reset handler initializes the stack pointer through only one instruction (MSR).
I know tcc doesn't handle ARM assembly, but is there a workaround for this situation (special macro? inline binary data)?
Else I have to provide an object created with GCC?
Thanks for your advice!

could you precise what exactly are you requesting? Since tcc generate ARMv4 and VFP it can run on processor with architecture ARMv4 and above with VFPv1 or above. Are you asking to support ARMv1 to ARMv3 architectures? Or to generate more optimised code for ARMv7? Or to support inline asm for ARM?

Best regards,

Good program!
It is be very useful for developing embbedded systems, if it would be have support of all set of ARM instructions:
for all arm (armv1-armv7) support and cortex-a8, cortex-a9 support. Also vfp instructions (v1, v2, v3), and neon.
