similar to: [klibc:master] mips: don't save floating point registers in setjmp / longjmp

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

Klibc FTBFS with '-mno-odd-spreg' on mips32(el) platforms, As it try to save/restore odd-number FPR. Indeed no other architectures save/restore FPR at all. It shouldn't be needed. --- usr/klibc/arch/mips/setjmp.S | 24 ------------------------ 1 file changed, 24 deletions(-) diff --git a/usr/klibc/arch/mips/setjmp.S b/usr/klibc/arch/mips/setjmp.S index 68eed19..21e4115 100644 ---

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: //

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.

James Cowgill dixit: >klibc does this when it saves all the FPU registers in its setjmp Hm, shouldn?t klibc not use the FPU at all?

Hi! The Netfilter project proudly presents: iptables 1.6.2 iptables is the userspace command line program used to configure the Linux 2.4.x and later packet filtering ruleset. It is targeted towards system administrators. This update contains accumulated bugfixes, a few new extensions and lots of translations via iptables-translate to ease migration to nftables.

As a new co-maintainer of klibc, I have just released version 2.0.5. The git repository remains at: https://git.kernel.org/pub/scm/libs/klibc/klibc.git A tarball will be available from the usual place later, but I'm not currently able to upload there. This new release fixes various build and run-time failures with current versions of Linux, gcc, and binutils on mips, sparc and x86; and
