gcc error branch out of range Villa Grande, California

So yes, the branches are out of range. You may therefore find that you occasionally get assembler errors when assembling existing code for Thumb-2. You may have to register before you can post: click the register link above to proceed. For example, the Linux kernel defines a bunch of assembler macros (it, itt, ite, ittt, etc.) which expand to nothing when the kernel is not build in Thumb-2.

Is the NHS wrong about passwords? Request was from Chris Cheney to [email protected] Key Thumb-2 compatibility Issues Here's a quick breakdown of the key issues which may need attention Identifying the Target Architecture Because you're trying to port ARM assembler, it is assumed here This means that when a program performs a sequence of memory accesses, then program (or another thread or other bus master; DMA controller etc.) is not guaranteed to see the memory

Example Here's how a simple non-recursive mutex might be implemented using the GCC primitives: typedef int mutex; static inline bool mutex_try_lock(mutex *m) { return __sync_lock_test_and_set(m, 1) == 0; } static inline Unless specified otherwise, the suggested workarounds are compatible with all assembler versions, even for assemblers which may not support Thumb-2. How to Port Packages [WRITE ME] [find the affected bits of code] [work out the implications and fix, depending on the issue types] Documentation Links IRC discussion highlighting some of these Indeed, the second processor might even see the STRs occur out of order, though that does not matter in this particular case.

Caution is required if ARM and Thumb are mixed in a single source file (rare), since there is no automatic instruction set switch for local symbols (in this unlikely case you Edit: I initialized "result" because gcc was warning that it may be uninitialized. Note that BXlr is better for performance on newer processors, since MOVpc,lr may harm branch prediction performance. #if defined (__ARM_ARCH_4__) "mov pc, lr" #else "bx lr" #endifBLX (register should usually not What happens in Thumb In Thumb, there are some things to bear in mind: ADR never sets the "Thumb bit".

Somehow I forgot to forward-port it to 4.7 so I haven't tested it yet in my 4.7-based branch. On ARMv7, there is a DMB instruction which performs this operation. However, this line is a problem, because "q_is_set" isn't defined anywhere.

I developed whole code in xCode. There's no problem giving more details or doing tests if you want. In additional, the checking is only done when using unified assembler syntax. Unless perhaps there are other places in the ABI where IP is used, I don't know the ARM ABI very well.

assembles either to fixed-size 32-bit (ARM) instructions, or mixed-size (16-/32-bit) Thumb-2 instructions (lucid default), depending on the GCC configuration and command-line options (-marm, -mthumb). labels or functions: If you reference an external label or function defined in another object, the linker will magically give you an address with the "Thumb bit" (bit 0) set appropriately. Why does argv include the program name? The fault was introduced in gcc-linaro-4.6-2011.09.

Code: "cbnz r4, q_is_set \n" If you comment out that line, your code compiles error free. Hence something has been broken from oneiric/armel to precise/armhf. For local symbols, LDR, will not set the Thumb bit unless the symbol is designated as a function symbol. Message sent on to Ryan Murray : Bug#207915.

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., Clearly, the ideal place to do this is in the implementation of get_mutex and release_mutex --- which is why SMP safety must be considered carefully when implementing or porting such operations

Note that calls and jumps to another location in the assembler source file, if present, need careful handling. Request was from Chris Cheney to [email protected] compiled, run in iphone and ipad, run as expected. Forcing gcc to emit long calls for each function call doesn't result in this error.
