Since at least GCC 4.4.3 (most architectures) and linux-2.6.19 (additional requirement for ARM), some compiler intrinsics are available which abstract these operations.

The primary reason for this is to understand the requirements for interworking (function calls between ARM and Thumb code) to work properly. http://stackoverflow.com/questions/23512087/assembler-messages-branch-out-of-range So yes, the branches are out of range.

As a general rule, do check for assembler warning messages (not just errors) when building the affected code. For C code, it's magic and will "just work", but for assembler, when you need to jump around, you need to do it the right way and not the wrong way... As far as i know, for "inline", they have to be local (with "%=") Code: static inline int saturated_subtract32_and_divide(int32_t a, int32_t b, int32_t c) __attribute__((always_inline)); int saturated_subtract32_and_divide(int32_t a, int32_t b, int32_t or add or sub or mov, but you should generally avoid doing anything else, and do not use the as a destination register in other operations, or attempt to push or

SWP and SWPB are not permitted in Thumb-2 code.

There are something like 50 constraints on the PowerPC due to various conditions. Using this sequence in Thumb code will not work correctly, since the value in lr will not be correct for an interworking return. #ifdefs may be required for compatibility with e.g., Information forwarded to [email protected], Debian GCC maintainers
what happened in testing?

For register shifts tie operands 0 and 1. (peephole2 for above): Check that register-controlled shifts have suitably tied operands. Backport r182621 from mainline 2011-12-21 Richard Earnshaw
The other right way to do a procedure return. Even worse, the compiler deletes the temporary .s file, so you can't see why it fails. Request was from Chris Cheney
