Control ARM prologue/epilogue assembly code emission

The Cortex-M4F (ARMv7M) does not have an explicit PUSH instruction, but only "STM". Verify that you call the compiler correctly for that core (flags -mcpu=cortex=M4 -mthumb). Paste the disassembly, step through the instructions with a debugger and explain why you believe that the

with an other mikrocontroller? Maybe that one is defect... This should definitely work (it does on my STM32F4 which is a Cortex-M4, too - i.e. has exactly the same core). I don't think GCC can be stopped from generating the "PUSH" instruction because it should work.

Atomic write - STM32

Hi, I'm currently working with a STM32F4 and try to implement atomic access to variables (e.g. mutexes). Currently, I disable all interrupts before accessing a mutex, and enable them afterwards. Now there exist the LDREX and STREX commands on the STM32, which seem to be perfect for my application. But how do I use them correctly? In the manual it says that an STREX *must* have the same address as the previous LDREX. So I still need to disable interrupts
