2013-05-15ARM: 7705/1: use optimized do_div only for EABIArnd Bergmann
In OABI configurations, some uses of the do_div function cause gcc to run out of registers. To work around that, we can force the use of the out-of-line version for configurations that build a OABI kernel. Without this patch, building netx_defconfig results in: net/core/pktgen.c: In function 'pktgen_if_show': net/core/pktgen.c:682:2775: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' net/core/pktgen.c:682:3153: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' net/core/pktgen.c:682:2775: error: 'asm' operand has impossible constraints net/core/pktgen.c:682:3153: error: 'asm' operand has impossible constraints Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-10-23[ARM] 5320/1: fix assembly constraints in implementation of do_div()Nicolas Pitre
Those inline assembly segments using the umlal instruction must have the & modifier so to be sure that a purely input register won't alias one of the registers used as input+output. In most cases, the inputs are still used after the outputs are touched, and most binutil versions insist on "rdhi, rdlo and rm must all be different" even for ARMv6+.
