Using GCC 4.7.2 in MINGW.
Cannot figure out the code generated for "
-mpreferred-stack-boundary=7". If you understand the generated code,
I compiled a sample program I wrote (attached), disassembled it, and
looked at the important instruction "sub esp,ALIGN_CONSTANT" in each of
With a -mpreferred-stack-boundary setting of 7, that means each function
should be aligned to 128 bytes, or 0x80 bytes.
But these are the results of ALIGN_CONSTANT
I would think ALIGN_CONSTANT should be closer to 128 minus a small value
for all 3 functions. But 0x178 and 0x8c?
