similar to: [PATCH] mips/setjmp.S don't save and restore float point registers

Any idea about it? It may be a serious problem, as some distributions are using FPXX by default.

This patch is needed to allow klibc to be compiled on a mips compiler configured to use the FPXX ABI (which is in GCC 5). In that ABI the odd numbered FPU registers cannot be used directly, but they can be accessed using the double word sdc1 and ldc1 instructions.

Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library

> So in summary, each step is ABI compatible with the previous step. The linker will ensure that the end-user doesn't try to do the second step before the first step is finished since it will refuse to link a binary that contains both O32 and O32+fp64. It will produce an O32 binary given a combination of O32+fpxx, and similarly a O32+fp64 binary given a combination O32+fpxx and O32+fp64.

Hi All, In SVN head, MipsISelDAGToDAG.cpp has the following optimization: // Operand is a result from an ADD. if (Addr.getOpcode() == ISD::ADD) { // When loading from constant pools, load the lower address part in // the instruction itself. Example, instead of: // lui $2, %hi($CPI1_0) // addiu $2, $2, %lo($CPI1_0) // lwc1 $f0, 0($2) // Generate: //

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:

Why are you reverting patches for any area that you have no authorization for ? No build was broken. This patch is fine. I am authorized to check in to the Mips area and Daniel is the maintainer for that area.

Hi Tom, I've got a few patches that I'd like to get into 3.5.2 if I can. * r230235 - [mips] Honour -mno-odd-spreg for vector insert/extract when MSA is enabled. o Fixes a failure in the test-suite when -mno-odd-spreg and -mmsa are used together. * r227089 - [mips] Enable arithmetic and binary operations for the i128 data type. o This fixes an instruction selection

Hi all, On behalf of Andes Technology Corp, I am proposing a backend targeting the NDS32 V3 ISA. NDS32 V3 ISA is a 16/32 bit mixed instruction set architecture that developed By AndesTech. You can find more information at the Andes website <http://www.andestech.com/>, and reference AndeStar ISA Manual (V3 ISA) from document download page <http://www.andestech.com/product.php?cls=9>.

I have an rsyslog server which is running Debian Stable, and its version of rsyslog is 4.6.4-2. All of my Debian Stable server can send log to it now. and run both nc $IP $PORT <<< "HELLO" and echo "HELLO" | nc $IP $PORT on client, I can get log on the server. While for my CentOS 5.7 server, nc $IP $PORT <<< "HELLO" works well, but echo
