| | | | | | | | | | | | | | | The attached patch adds support for compiling arm uClibc as pure Thumb code. This is needed because some recent ARM codes do not implement traditional ARM mode. Specifically: * Cortex-M1 - An extremely minimal FPGA based core that only implements Thumb-1 (aka ARMv6-M). * Cortex-M3 - A Thumb-2 only ARMv7-M core. Most of uClibc already builds in Thumb mode, all that is left are a handful of assembly bits. Tested on arm-uclinuxeabi.

| | | | | | | | | | | | | | | | | | This patch changes all cases where the ARM assembler mov pc,rx instructions are used to ensure that the thumb/arm interwork change of process more works - in essence mov pc,rx needs to become bx rc. The ldr pc or ldm rx, {pc} instructions are not changed - this is fine on ARM >=v5 but will fail to restore thumb mode on ARM v4T, i.e. this code will not provide support for thumb on ARM v4T. One mov pc is left in resolve.S, this is fixed in a different patch - thumb-resolve.patch The changes are protected by __THUMB_INTERWORK__ - the original mov instruction will work on newer architectures and is required on arch v4 (not v4t) and earlier - those which did not support thumb - so this is safe. See gcc lib1asmfuncs for a more exact test.

wouldn't run on my little arm7tdmi/uClinux boards, since without vfork working, nothing works on uClinux. It took me forever to find this, since other problems were hiding this one. Big, huge, sigh of relief. -Erik
