[Bug target/111755] The built-in memset function in GCC inadvertently generates code like "vst1.8 {d8-d9}, [sp:64]", which assumes an 8-byte alignment on the stack pointer $sp, leading to alignment violations

I apologize, but I will retract this report. I've realized that the IRQ handler
call of a certain RTOS I'm using is invoking with $sp as a multiple of 4, not
8. This violates the ARM ABI convention.
