question on bfd - arch & mach

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I am going through the binutils code base specific to arm & aarch64. Please give some insight on below questions. 1. In the struct bfd_arch_info {...} (in bfd/bfd-in2.h) there are two fields 'enum bfd_architecture arch' and 'unsigned long mach'. I went trough the binutils porting guide (by MR.Swami.Reddy(a)nsc.com) which says 'arch' is for architecture & 'mach' is for machine value. At present in the bfd/bfd-in2.h :- arch = bfd_arch_aarch64 and mach = bfd_mach_aarch64 or bfd_mach_aarch64_ilp32. But what these fields really means ? What is the difference between 'arch' and 'mach'? Lets say instruction set architecture is ARMv8 (also known as aarch64 for 64 bit- if I am not wrong). Then we have specific implementation of this like cortex53, cortex57, Cavium ThunderX etc. With respect to this what will be the value of arch = ? and mach = ? 2. In the include/opcode/arm.h the 'arm_feature_set' is defined as a structure where as in include/opcode/aarch64.h 'aarch64_feature_set' is defined as unsigned long. Is there any specific reason for this? Why structure definition was not followed in aarch64 ? typedef struct { unsigned long core; unsigned long coproc; } arm_feature_set; typedef unsigned long aarch64_feature_set; 3. Also I see that in the case of arm, 'mach' values are derived from cpu extension value specified in that 'arm_feature_set' structure. For example. if (ARM_CPU_HAS_FEATURE (cpu_variant, arm_cext_iwmmxt2)) mach = bfd_mach_arm_iWMMXt2; Whereas in aarch64 mach is derived based on API type (64 or 32). Any reason for this ? mach = ilp32_p ? bfd_mach_aarch64_ilp32 : bfd_mach_aarch64; Thanks in advance. -- with regards, Virendra Kumar Pathak

Before r221297, in merge_decls() DECL_RTL_SET_P (olddecl) was true which resulted in call to make_decl_rtl() causing ICE. After r221297, DECL_RTL_SET_P (olddecl) is 0, which doesn't result in call to make_decl_rtl() so no ICE is produced. However, DECL_COMMON is still incorrectly set in merge_decls() because it copies newdecl into olddecl. - Will post upstream for review after final testing on x86 and ARM. * Misc (6/10) - Exams

Hi, I tried on abe 'stable' branch and with below configuration build was successful. ../abe/configure --with-fileserver=148.251.136.42 --with-remote-snapshots= http://148.251.136.42/snapshots-ref ../abe/abe.sh --target aarch64-linux-gnu --build all (Additionally I had to increase the wget_timeout=100) But on master branch, with below commands (as suggested in above mail) following error were observed. ../abe/configure --with-fileserver=148.251.136.42 --with-remote-snapshots=/snapshots-ref ../abe/abe.sh --target aarch64-linux-gnu --build all ERROR (#144): fetch_http (md5sums doesn't exist and you disabled updating.) Looks like following commit is causing problem on the abe master branch.

Correct linux kerenl for eglibc in Linaro tool chain

by Ganesan, Aravind

Hi Guys, I have two questions: (1) I have download gcc-4.9 tool chain from http://releases.linaro.org/14.08/components/toolchain/binaries. The kernel for the release (http://releases.linaro.org/14.08/components/kernel/linux-linaro) is 3.16. So can we assume the kernel headers found in the tool chain installation from the link above belongs to linux version 3.16? (2) Also, I ubuntu wiki indicates that starting with Ubuntu 12.04 they are using linaro gcc packages for arm64 (https://wiki.ubuntu.com/ToolChain). Is there an easy way to find what linaro-release (for tool chain) will be compatible with Ubuntu 14.10 aarch64 image? Thanks, Aravind -- Qualcomm Innovation Center, Inc.

writing a new Machine Description file (e.g cortex-a57.md) in gcc

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I am new to gcc development. I am trying to write a new md file describing pipeline information for a processor. Please suggest some good reference document for understanding machine description file. Few questions from cortex-a53.md file: For first integer pipeline following is defined - (define_cpu_unit "cortex_a53_slot0" "cortex_a53") Is name cortex_a53_slot0 is a keyword or it is any general string? Is there any convention in choosing names for cpu units? If ‘cortex_a53_slot0’ a general string, how assembler knows it is first integer pipeline? How these *.md files are used? When they are compiled and how they are used? How to verify an md file for a processor is written correctly or not? How to test it? What other design consideration must be kept in mind while writing a new md file? Thanks. with regards, Virendra Kumar Pathak

[ANNOUNCE] Linaro GCC 4.9 2015.04 snapshot re-spin

by Yvan Roux

This is a re-spin of the Linaro GCC 4.9 2015.04 source package snapshot. The re-spin of this snapshot includes a new configure-time option to enable by default a workaround for Cortex-A53 erratum number 843419 and options to explicitly disable or enable it during compilation. This snapshot tarball is available on: http://snapshots.linaro.org/components/toolchain/gcc-linaro/4.9-2015.04-1 Original release notes for GCC 4.9 2015.04 snapshot: The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2015.04 snapshot of the Linaro GCC 4.9 source package. Linaro GCC 4.9 2015.04 is the first Linaro GCC source package snapshot in the 4.9 series. It is based on FSF GCC 4.9.3-pre+svn222035 and includes performance improvements and bug fixes. With the imminent release of ARMv8 hardware and the recent release of the GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and performance of the compiler as the FSF GCC compiler.

PR65837 - patch to lto-wrapper rejected. - Another hack to pass driver's argv to lto-wrapper via another environment variable COLLECT_GCC_OPTIONS_DRIVER rejected by Richard. - Ramana and Richard pointed out the proper fix would be to handle target attributes in ARM backend. - I could try extending Christian Bruel's target attribute patches for fpu options after they're checked in which would then fix the PR. chromium LTO build - Many instances of same error message during LINK chrome: chrome.ltrans0.s:18399164: Error: Thumb2 branch out of range chrome.ltrans0.s:9671243: Error: branch out of range works fine for non-lto. A similar issue, occurred for v8 LTO build - PR65778, but it was marked resolved invalid. - chromium builds with LTO for chrome component. - ld.bfd segfault while building chromium with LTO not reproducible with master. - non-LTO build undefined reference to libattr1 functions not reproducible with ld.bfd master.
