Hi Matthew, > * When the option is on the linker will only use BLX if the target > architecture (derived from the object files) is v6T2, v7, or > greater. This does not seem right to me. The erratum only applies to the ARM1176JZ-S and ARM1176JZF-S processors and only to Thumb BLX instructions. Disabling the use of BLX in ARM mode or for pre-ARM11 cores will generate needlessly larger code. Also when you check the Tag_CPU_arch value, please use the enum names, not the integer values. Cheers Nick
