Hello, I built a llvm toolchain for ARM and I'm trying to build a simple application on ARM using LLVM. When I compiled the code, it has the following message and the binary code has a segmentation fault when it is executed. /tmp/ccJPjMe4.s: Assembler messages: /tmp/ccJPjMe4.s:4250: rdhi, rdlo and rm must all be different /tmp/ccJPjMe4.s:4589: rdhi, rdlo and rm must all be different /tmp/ccJPjMe4.s:4694: rdhi, rdlo and rm must all be different /tmp/ccJPjMe4.s:4899: rdhi, rdlo and rm must all be different /tmp/ccJPjMe4.s:4915: rdhi, rdlo and rm must all be different Any idea?

Hi James/Tim, I am trying to add a patterns for SMLALBB I think these two assembly patterns can be reduced to SMLALBB using tablegen. 1) smulbb r2, r3, r2 adds r0, r2, r0 (RdLo) asr r3, r2, #31 adc r1, r3, r1 (RdHi) ==> smlalbb r0, r1, r3, r2 I have added pattern in def SMLALBB : AMulxyI64< ..... as below :- [] modified to ---> [((set GPR:$RdLo, (ARMaddc (set GPR:$Rd, mul GPR:$Rn, GPR:$Rm), GPR:$RdLo)), (set GPR:$RdHi, (ARMadde (sra G...

I'm getting following errors while cross compiling llvm for ARM. Please help since it is urgent and critical My gcc version is 4.2.0, 32bit Linux and target is ARM Configure options are: ./configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --target=armv7fl-montavista-linux-gnueabi --enable-cross --with-sysroot=/home//arm_v7_vfp_le/target/
