Provide an option to have a PROVIDE_HIDDEN (linker script) entry for each weak symbol. This option solve an error in x86_64 where the linker optimizes pie generate code to be non-pie because --emit-relocs was used instead of -pie (to reduce dynamic relocations).

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

Hi, dears, I am processing some data with 60 columns, and 286,730 rows. Most columns are numerical value, and some columns are categorical value. It turns out that: when ntree sets to the default value (500), it says "can not allocate a vector of 1.1 GB size"; And when I set ntree to be a very small number like 10, it will run for hours. I use the (x,y) rather than the (formula,data).

Oh, one thing I forgot to mention: ReadOnly objects are also counted as small data globals on PPC (on top of BSS, Data, Common). That's what the r2 base is for (.sdata2, defined to be constant data). 32-bit immediate loads take 2 ops minimum on PPC, so even constant loading benefits from small data. It'd be handy to add a third argument containing what kind would normally be returned:

Peter, Thanks for the great feedback! > The first is the use of a custom suffix, all other linker conventions, that I know of, use prefixes as these are much easier and faster to match against names. > This can be important in large programs compiled -ffunction-sections as there can be millions of sections to match. I understand the reason of having these conventions in linkers. On the

Changes: - patch v4: - Simplify early boot by removing global variables. - Modify the mcount location script for __mcount_loc intead of the address read in the ftrace implementation. - Edit commit description to explain better where the kernel can be located. - Streamlined the testing done on each patch proposal. Always testing hibernation, suspend, ftrace and kprobe to

Changes: - patch v5: - Adapt new crypto modules for PIE. - Improve per-cpu commit message. - Fix xen 32-bit build error with .quad. - Remove extra code for ftrace. - patch v4: - Simplify early boot by removing global variables. - Modify the mcount location script for __mcount_loc intead of the address read in the ftrace implementation. - Edit commit description to

Hey, We would like to propose an idea that would help security harden applications that define custom sections. Motivation and Background In Chromium we have a garbage collector that implements some RTTI machinery in the form of a table. This table is used by the collector to trace and finalize garbage collected objects. We're thinking of using __attribute__((section(...))) so that the table

We use .note descriptors with ELF on OpenVMS.  We have self-describing entries with tags and lengths.  The compiler encodes stuff for the linker such as compiler version, compilation date-time, module name, final severity of the compilation, etc.  The linker itself then adds/modifies the .note entries to insert linker version, link date/time, etc.  We also use .notes to record floating point

Changes: - patch v3: - Update on message to describe longer term PIE goal. - Minor change on ftrace if condition. - Changed code using xchgq. - patch v2: - Adapt patch to work post KPTI and compiler changes - Redo all performance testing with latest configs and compilers - Simplify mov macro on PIE (MOVABS now) - Reduce GOT footprint - patch v1: - Simplify ftrace

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:

I've prepared a preliminary patch with the intention of implementing PPC-EABI subtarget features for applications that run in a standalone embedded environment. https://reviews.llvm.org/D26344 The most significant difference compared with the SVR4 ABI is the use of SDA (small data area). This allows full-word constants and data to be grouped into small-data sections accessed using relocated

Changes: - patch v2: - Adapt patch to work post KPTI and compiler changes - Redo all performance testing with latest configs and compilers - Simplify mov macro on PIE (MOVABS now) - Reduce GOT footprint - patch v1: - Simplify ftrace implementation. - Use gcc mstack-protector-guard-reg=%gs with PIE when possible. - rfc v3: - Use --emit-relocs instead of -pie to reduce
