2008-03-26Paul Brook writes:Bernhard Reutner-Fischer
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.
2008-01-17A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt
a problem where the linker was trying to use the wrong symbol name for the init function. Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960, microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets which define SYMBOL_PREFIX as _. Remove defines and undefs from uClibc_arch_features.h of each target. Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.

The patch below tweaks the ARM nommu startup code so that doubleword stack alignment is preserved. This is required on EABI targets.

applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file.

2006-11-10arm thumb:Eric Andersen
Put the call_via_rx code into each executable - call_via_ip cannot possibly work if called through the PLT! ldso requires this code too as it is not linked with the crt stuff and thumb ldso does make calls via a register. The patch puts the code into crti.S so that it is linked into every normally built application (if thumb or interworking is selected). This is only 30 extra bytes and it works - the previous code did not because nothing both implemented and exported the APIs (they were in libgcc, but not in the version script). crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this is essential for thumb support because the .init and .fini sections must use arm or thumb code to match the compilation of the libraries. Note that code which pushes stuff into .init or .fini must be compiled with or without -mthumb to match the uclibc compilation - and gcc itself (which does do this) must therefore be compiled to match.

This patch fixes some of the ARM EABI code to be interworking-safe, using bx where appropriate. (This code went in around the same time as the Thumb patches, hence not being fixed by those patches.)

2006-01-31John Bowler writes in Bug 385:Mike Frysinger
The patch fixes up the .align directives to '2' (i.e. a multiple of 4) not '4' (a multiple of 16 - apparently an error since it seems to be unnecessary, there is no advantage here in cache line alignment). this is an arm "feature" ... the value given to .align is not in bytes: .align 4 in arm means .align 2 ^ 4
2006-01-31John Bowler writes in Bug 385:Mike Frysinger
This is a work round for a fairly serious GCC compiler bug - when the syscall assembler overwrites r7 (required on thumb) the compiler fails to protect the register when it is using it as a frame pointer.
2006-01-31John Bowler writes in Bug 385:Mike Frysinger
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.
