Hello everybody
there is a compilation error with GCC >= 3.4 and all U-Boot ARM targets like motorola mx1ads (arm920t). the ARM '-mshort-load-bytes' compilation flag is deprecated and no more supported. Since all referenced ARM cpus are based on the ARMv4 core or higher, It is possible to remove this flag. the binary code produced is compatible (as described in GCC doc). I checked it with the ELDK GCC 3.3.3 and a GCC 3.4.2 without problem on a Freescale imx board.
Note: There is an alternate GCC flag to solve this problem (- malignment-traps) but this flag seems to be deprecated with the recent GCC 4.
Actually i'm interested to solve the problem with the arm920t. For developers this is the list of affected files/architectures and hereafter a patch to support GCC 3.4 and upper: cpu/arm720t/config.mk cpu/arm920t/config.mk cpu/arm925t/config.mk cpu/arm926ejs/config.mk cpu/ixp/config.mk cpu/lh7a40x/config.mk cpu/pxa/config.mk cpu/s3c44b0/config.mk cpu/sa1100/config.mk
Feedbacks are welcome. Thanks
Best regards, Eric Jarrige
