I tested the changes as in revision 59f52c69d79b10c81913e837ecb14dad0c5fe264:
I wasn't sure what exactly should be tested, this is the test case I used: http://dpaste.dzfl.pl/c362e632 (not sure why it doesn't compile on dpaste, it works with my local dmd and gdc installation) This was the output: -------- foo Test test 42 -0.481002 42 Hello [10, 0, 0, 0, 200, 69, 246, 190, 0, 1] -------- * Formatting the struct works, the vprintf example works as well. * Test2 fails, the float is not read correctly. Could be related to the hardfloat API? (it does work on x86 dmd, can't text x86 gdc right now). More complicated examples with floats usually lead to segmentation faults. * Test3 does not work either. Seems passing static arrays doesn't work. However, this also doesn't work on x86/dmd so maybe I'm doing something wrong? It seems this is alignment related though: I guess va_arg always expects the arguments to be aligned, but ubyte[10] isn't aligned? If the value passed to the function is a ulong, but read as a ubyte[8] everything is fine (on arm and on x86/dmd), if the value is passed as a ubyte[8] and read as a ubyte[8] it doesn't work: -------- ubyte[8] c = cast(ubyte[8])[0,1,2,3,4,5,6,7]; test3("", 42, "Hello", *(cast(ulong*)&c)); //WORKS --------
