* replaced bf specific usleep replacement with one using cycle counts to be stable while changing optimization levels * uint32_t signature on usleep since the register read is 32bit... * enabled -O2 for ctb and mythen + a few additional warnings * configure stack size for blackfin servers to 256kB instead of the default 4kB * enable opt for JF and Moench, ratemax make local for eiger * fixed misplaced volatile on Beb_Read32 * removed dead code in eiger server (which had 2 byte read passt end), usleep_bf returns -1 for sleeps that can't be represented * deal with fall through of table filling in ratecorr table * memory clobber for inline asm and added flags on eiger * -O2 for gotthard and xilinx * fixes to remove the new warnings * fixed new eiger warnings * binaries in --------- Co-authored-by: Dhanya Thattil <dhanya.thattil@psi.ch>
