This patch shuffles the M0 Makefile flags around a bit trying to make their purpose clearer and remove duplication. Since all three build steps (compiling, assembling, linking) actually call GCC, remove the misleading aliases $(AS) and $(LD) to avoid confusion that those tools might be called directly. Split flags into a common group that has meaning for all three steps and separate variables specific to each step. Remove -nostartfiles which is a strict subset of -nostdlib. Also add explicit parameters for -mfloat-abi=soft, -fomit-frame-pointer and -fno-common. If omitted these settings depend on the toolchain's built-in default and cause various problems if they resolve to unexpected values. Signed-off-by: Julius Werner <jwerner@chromium.org> |
