2008-05-30- Fix gcc glitch with mremap and IMA.Bernhard Reutner-Fischer
For -combine, make sure that we don't pollute our non-varargs mremap decl with some vararg decl from later in the TU by putting ours after anybody else who is picking up mman.h. This is admittedly a small work-around.. smallish testcase: $ cat bug.h extern void *mremap (void*, unsigned, unsigned, int, ...); $ cat bug1.c #include "bug.h" int whatever; $ cat bug2.c #define mremap _hidemremap #include "bug.h" #undef mremap void *mremap (void*, unsigned, unsigned, int, void*); $ gcc -c bug1.c bug2.c $ gcc -c bug1.c bug2.c -combine bug2.c:4: error: conflicting types for ‘mremap’ bug.h:1: error: previous declaration of ‘mremap’ was here

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.

This patch uses the HIDDEN_JUMPTARGET instead of the __GI_ prefix in AVR32 assembler files. This is done to follow the code style in uClibc. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>

allocations, dma_memcpy to move stuff between L1 and main memory, and a new structure to describe the global data in L1 scratchpad memory.
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 following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica. For more information, please visit: www.linux-xtensa.org.

2008-01-05michael_d writes in #1874: Mike Frysinger
On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

getcwd syscall has an off-by-one allocation bug. As a result, sometimes the returned string has garbage at the end.
