gcc-5 git branch

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I see two git branches for GCC-5 at https://git.linaro.org 1. https://git.linaro.org/toolchain/gcc.git/shortlog/refs/heads/gcc-5-branch 2. https://git.linaro.org/toolchain/gcc.git/shortlog/refs/heads/linaro/gcc-5-b… What is the difference between these two branches ? Which branch should be used for development ? Is it branch (1) refers to GCC upstream branch for GCC5 & branch (2) is linaro version of branch (1). Please comment. -- with regards, Virendra Kumar Pathak

abe: cross native toolchain compilation for aarch64-linux-gnu

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I am trying to build a cross-native toolchain for AARCH64 using ABE build framework. By cross native I mean that toolchain will be build on 0x86 (Red hat Santiago 6.4), it will run on AARCH64 (Juno) and will produce binaries to be run on AARCH64 (Juno) (If I am not mistaked) --build=0x86, --host=AARCH64, --target=AARCH64 Steps followed: 1. I built a cross toolchain first ../abe/configure ../abe/abe.sh --target aarch64-linux-gnu --build all --release 2015.05.29 --tarbin --disable update 2. Added the above cross toolchain (bin path) in the PATH 3. To build to cross-native ../abe/configure ../abe/abe.sh --host aarch64-linux-gnu --target aarch64-linux-gnu --build all --release 2015.06.01.native --tarbin --disable update But after some time, I got following error and compilation hanged. make: Leaving directory `/home/user_name/vpathak/build_abe/builds/aarch64-linux-gnu/aarch64-linux-gnu/gcc.git~linaro-4.9-branch-stage1' RUN: copy_gcc_libs_to_sysroot "/home/user_name/vpathak/build_abe/builds/destdir/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc --sysroot=/home/user_name/vpathak/build_abe/sysroots/aarch64-linux-gnu" /home/user_name/vpathak/abe/lib/make.sh: line 962: ./builds/destdir/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc: cannot execute binary file Am I missing something ? Please help. However with the following hack in the abe, I am able to compile cross-native toolchain for aarch64-linux-gnu. In the abe code base: ------------------------------------------------------------------------------------------------------- lib/make.sh Function copy_gcc_libs_to_sysroot() gcc_exe="`find -name ${target}-gcc`" - libgcc="`${gcc_exe} -print-file-name=${libgcc}`" + #libgcc="`${gcc_exe} -print-file-name=${libgcc}`" + libgcc="/home/user_name/vpathak/build_abe/builds/destdir/aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/4.9.3/libgcc.a" Since './builds/destdir/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc' is native toolchain it will not run on 0x86. Thus libgcc will be empty. Therefore I hard-coded libgcc path. ------------------------------------------------------------------------------------------------------- I had to disable gdb compilation. This error I faced while compiling cross-native compilation only. Cross compilation is successful on the same 0x86 machine. checking for library containing waddstr... no configure: error: no enhanced curses library found; disable TUI make: *** [configure-gdb] Error 1 make: Leaving directory `/home/user_name/vpathak/build_abe/builds/aarch64-linux-gnu/aarch64-linux-gnu/binutils-gdb.git~linaro_gdb-7.8-branch-gdb' WARNING: Make had failures!

Tool for checking coding style in Linaro Toolchain

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, Is there any tool for checking coding style of the patches submitted to the Linaro Toolchain ? In other word is there any equivalent of Linux checkpatch.pl in Linaro Toolchain (GCC, Binutils etc) ? If yes, please let me know. If not, then in general how people check the coding style of the patches they submit to Linaro Toolchain (GCC, Binutils etc). I assume manual inspection (line by line) may be very tedious thing to do. Thanks. -- with regards, Virendra Kumar Pathak

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

# Progress # * TCWG-517, GDB AAarch64 record/replay. Ongoing. [3/10] Takes over from Omair, complete test cases and update patches. Rewrite the test case using gcc inline assembly. Happen to see that AAarch64 doesn't have CPSR register but GDB thinks it has. This should be fixed separately later. * Think about GDB version in next linaro toolchain release. [3/10] The next linaro release is on July/Aug and the next GDB FSF release 7.10 will be on mid of June.

Re: 502 connecting to abe.tcwglab.linaro.org

by Virendra Kumar Pathak

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. On removing it, build successfully downloaded the packages from 148.251.136.42. commit 5a5ab3582851d52d903846d34c79850f5d7ebda5 don't try to fetch anything is updates are disabled.

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
