2008-04-27build system: improve install_headers.Denis Vlasenko
Now it uses dedicated script instead of inline makefile commands, which helps readability. It also installs asm[-generic] and linux subdirs from kernel headers (previously it had to be done separately). Lastly, it passes each uclibc header thru unifdef, which strips #ifdef UCLIBC_INTERNAL conditional from headers. Currently it's a no-op (no such #ifders in tree). The plan is to have libc_hidden_proto(foo) migrated to headers and guard them by these #ifdefs.

2008-04-15amd64 string ops: use alignment more carefully, and comment it.Denis Vlasenko
By capping max padding to not be bigger than three next insns, we avoid having ridiculously big NOPs like this one: 53:66 66 66 66 2e 0f 1f nopw %cs:0x0(%rax,%rax,1) 5a:84 00 00 00 00 00 which was bigger than next three insns combined!

2008-04-15amd64 string ops: replace some instructions by smaller ones,Denis Vlasenko
e.g. testb $0xff, %cl -> testb %cl, %cl
2008-04-12Functions should be either exported in public .h filesDenis Vlasenko
and marked with libc_hidden_proto/def(), or not be exported in .h files and be hidden (or even static if possible). We have five functions which violate this. Fixing: netdb.h: export ruserpass() rpc/rpc.h: export xdr_accepted_reply() and xdr_rejected_reply() make inet_ntoa_r static function (it is not exported in any .h file) make _time_tzset hidden function (it is not exported in any .h file)

2008-04-09Remove vestigial locking init from sprintf routines.Denis Vlasenko
2008-04-09Factor out the core of vprintf() into separate functionDenis Vlasenko
vprintf_internal, so that: * vprintf() does locking and __STDIO_STREAM_TRANS_TO_WRITE thing, then calls vprintf_internal * vsnprintf, vdprintf.c, vasprintf.c use vprintf_internal directly This makes sprintf faster (since it doesn't do any locking) and stops it from pulling in fseek in static compile.

Either by first compiling objects and linking those or by just passing the source to create the desired binary (this patchlet does the latter). Fixes cosmetic glitch by just not building individual .o (in pwd, at least).

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.

2008-03-13avr32: Use HIDDEN_JUMPTARGET() macro in bzero.SHaavard Skinnemoen
Also, remove the hidden __memset symbol from memset.S
2008-03-13From: Geoffrey Wossum <geoffrey@pager.net>Haavard Skinnemoen
Found a problem with the AVR32 optimized bzero() code. Due to a missing #include, it actually generated no code.
