# Progress # * TCWG-984, PR 20939, GDB aborts if there is an error in disassembly. Done. All patches are committed to mainline. [3/10] * Patch reviews, a lot, [5/10] ** Hold one of ILP32 BFD patch because it may affect aarch64 GDB, Reviewed ILP32 GDB patch, and convince them not to add new target descriptions for ILP32, to make our life easier in the future. Otherwise, we need two copies of target description for each new hardware feature, such as v8.3, SVE, etc. ** Try to hold one disassembler options patch, which affects ARM and GDB. Gave some comments on the interface design, but looks I am late. ** Finish the review on DW_OP_implicit_value. Met some grey area in DWARF spec. * Atomicity of concurrent modification on ptrace. [1/10] It is unclear weather debugging can modify memory for one thread while other threads are running. After the discussions with some kernel guy, PTRACE_POKETEXT is atomic, but GDB use it in a non-atomic way when writing 2-byte aligned 32-bit thumb-2 instruction. Suggested a workaround upstreams. * Misc, meeting [1/10] # Plan # * ILP32 patch review. * Carefully read IBM's kernel debugging patches. * Set up AArch64 bare debugging with GDB, OpenOCD, JTAG and HiKey. Soldering is needed. -- Yao Qi

[TCWG-614] Range extension thunks - LLD now uses synthetic sections for Thunks. ARM Thunks now have symbols and mapping symbols. As a side-effect we can now create local symbols in synthetic sections so I've added them to the ARM PLT sections. [Misc] - Wrote 3 lines of lld 4.0 release notes for ARM - Some upstream patch review in rtdyld and ilp32 support in the assembler - Presented my personal Linaro objectives to the TCWG leads. Plans for next week: - Complete Fosdem presentation, will be leaving early Friday to catch the Eurostar - Respond to any post commit review comments on Thunks - Start work on range extension thunks, the previous commits to use synthetic sections were pre-requisites to range extension thunks, but added little new user-visible functionality. Planned absences: - Fosdem 2017 will need to leave early on Friday 4th Feb - Holiday 21st Feb to 1st March - Linaro Connect 6th to 10th March Euro LLVM 27-28 March (Linaro's request and cost-code)

[TCWG-614] Range extension thunks Started process of upstreaming the conversion of Thunks to SyntheticSections. - Patch 1 of 3 committed, move Thunk Creation later in the link step. - Patch 2 of 3 add support for local symbol creation in upstream review - Patch 3 of 3 waiting for patch 2 Made a patch to output mapping symbols in PLT to test local symbol creation. Not recommending this for inclusion in lld yet, but have included as a way of testing 2. Responded to comment on implementation and overall Thunks proposal. Plans for next week: Yet more range extension work, hope to get patches 2 and 3 above committed.

[TCWG-614] Long branch thunks: Implemented a prototype of the existing Thunk implementation using Synthetic (Linker created sections) and moved it close to the area it will need to go for Long Branch Thunk work. Worked on this exclusively all week. Plans for next week: [TCWG-614] Long branch thunks: Tidy up and refactor prototype to a point where I can post for upstream review. This won't be long-branch thunk support but it will be a significant intermediate step. Do a draft plan of Connect submission and decide how long I need.

Does Linaro's GCC 4.9 include Crypto extensions and intrinsics?

Please forgive my ignorance. I'm working on a Pine64 dev-board Pine64 supplies Linaro's GCC 4.9.2 toolchain. I am catching a compile error, and I am trying to determine why. Does Linaro's GCC 4.9 provide AES and SHA intrinsics? ********** $ uname -a Linux pine64 3.10.102-2-pine64-longsleep #66 SMP PREEMPT Sat Jul 16 10:53:13 CEST 2016 aarch64 GNU/Linux $ gcc --version gcc (Debian/Linaro 4.9.2-10) 4.9.2 Copyright (C) 2014 Free Software Foundation, Inc. ********** $ CFLAGS="-DMBEDTLS_HAVE_ARMV8A_CE=1" make DEBUG=1 V=1 CC aes_armv8a_ce.c aes_armv8a_ce.c: In function 'mbedtls_armv8a_ce_aes_crypt_ecb': aes_armv8a_ce.c:65:4: warning: implicit declaration of function 'vaeseq_u8' [-Wimplicit-function-declaration] state_vec = vaeseq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c:65:14: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaeseq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c:67:4: warning: implicit declaration of function 'vaesmcq_u8' [-Wimplicit-function-declaration] state_vec = vaesmcq_u8( state_vec ); ^ aes_armv8a_ce.c:67:14: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaesmcq_u8( state_vec ); ^ aes_armv8a_ce.c:74:13: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaeseq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c:84:4: warning: implicit declaration of function 'vaesdq_u8' [-Wimplicit-function-declaration] state_vec = vaesdq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c:84:14: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaesdq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c:86:4: warning: implicit declaration of function 'vaesimcq_u8' [-Wimplicit-function-declaration] state_vec = vaesimcq_u8( state_vec ); ^ aes_armv8a_ce.c:86:14: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaesimcq_u8( state_vec ); ^ aes_armv8a_ce.c:93:13: error: incompatible types when assigning to type 'uint8x16_t' from type 'int' state_vec = vaesdq_u8( state_vec, roundkey_vec ); ^ aes_armv8a_ce.c: In function 'mbedtls_armv8a_ce_gcm_mult': aes_armv8a_ce.c:138:2: warning: implicit declaration of function 'vmull_high_p64' [-Wimplicit-function-declaration] r1 = (uint8x16_t)vmull_high_p64( (poly64x2_t)a_p, (poly64x2_t)b_p ); ^ aes_armv8a_ce.c:138:2: error: can't convert between vector values of different size aes_armv8a_ce.c:141:2: error: can't convert between vector values of different size t0 = (uint8x16_t)vmull_high_p64( (poly64x2_t)a_p, (poly64x2_t)t0 ); ^ aes_armv8a_ce.c:150:2: error: can't convert between vector values of different size t0 = (uint8x16_t)vmull_high_p64( (poly64x2_t)r1, (poly64x2_t)p ); ^ Makefile:170: recipe for target 'aes_armv8a_ce.o' failed make[1]: *** [aes_armv8a_ce.o] Error 1 Makefile:17: recipe for target 'lib' failed make: *** [lib] Error 2 ********** CC sha1_armv8a_ce.c sha1_armv8a_ce.c: In function 'mbedtls_armv8a_ce_sha1_process': sha1_armv8a_ce.c:99:2: warning: implicit declaration of function 'vsha1h_u32' [-Wimplicit-function-declaration] e1 = vsha1h_u32( a ); ^ sha1_armv8a_ce.c:100:2: warning: implicit declaration of function 'vsha1cq_u32' [-Wimplicit-function-declaration] abcd = vsha1cq_u32( abcd, e, wk0 ); /* 0 */ ^ sha1_armv8a_ce.c:100:7: error: incompatible types when assigning to type 'uint32x4_t' from type 'int' abcd = vsha1cq_u32( abcd, e, wk0 ); /* 0 */ ^ sha1_armv8a_ce.c:102:2: warning: implicit declaration of function 'vsha1su0q_u32' [-Wimplicit-function-declaration] w0 = vsha1su0q_u32( w0, w1, w2 ); ^ sha1_armv8a_ce.c:102:5: error: incompatible types when assigning to type 'uint32x4_t' from type 'int' w0 = vsha1su0q_u32( w0, w1, w2 ); ^ sha1_armv8a_ce.c:106:7: error: incompatible types when assigning to type 'uint32x4_t' from type 'int' abcd = vsha1cq_u32( abcd, e1, wk1 ); /* 1 */ ^ sha1_armv8a_ce.c:108:2: warning: implicit declaration of function 'vsha1su1q_u32' [-Wimplicit-function-declaration] w0 = vsha1su1q_u32( w0, w3 ); ^ sha1_armv8a_ce.c:108:5: error: incompatible types when assigning to type 'uint32x4_t' from type 'int' w0 = vsha1su1q_u32( w0, w3 ); ^ sha1_armv8a_ce.c:109:5: error: incompatible types when assigning to type 'uint32x4_t' from type 'int' w1 = vsha1su0q_u32( w1, w2, w3 ); ^ ... ********** $ grep -IR vaeseq_u8 /usr/include /usr/include/clang/3.5.0/include/arm_neon.h:__ai uint8x16_t vaeseq_u8(uint8x16_t __p0, uint8x16_t __p1) { /usr/include/clang/3.5.0/include/arm_neon.h:__ai uint8x16_t vaeseq_u8(uint8x16_t __p0, uint8x16_t __p1) { /usr/include/clang/3.5/include/arm_neon.h:__ai uint8x16_t vaeseq_u8(uint8x16_t __p0, uint8x16_t __p1) { /usr/include/clang/3.5/include/arm_neon.h:__ai uint8x16_t vaeseq_u8(uint8x16_t __p0, uint8x16_t __p1) { $

=== This Week === Back from month long holiday had a surgery during this period. Add Pine64 as tester to LLDB buildbot [TCWG-1011] [3/10] -- Configure Pine64 with Ubuntu 16.04 image -- Configure network on Pine64 to be used with LLDB buildbot -- Configure Pine64 for AArch32 mode execution -- Configure LLDB buildbot to include Pine64 as tester in both AArch32 and AArch64 modes. -- Run buildbot with Pine64 and monitor stability Monitor LLDB buildbot for minimum down time. [TCWG-712] -- Return from break reset buildbot and testers. Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] [2/10] -- Some tests pass when run individually. -- Some tests fail only when run in testsuite, similar steps pass when run using LLDB commandline. LLDB Arm/AArch64 Investigate and fix testsuite crashes (Pine64 Crashes) [TCWG-792] [1/10] -- LLDB crashing unexpectedly on Pine64 as well. -- Initial investigation suggests test run fine individually and in single thread mode. Meetings and other Miscellaneous Activities [1/10] -- Browse through email backlog. -- Prepared a future ToDo list. BUD17 Travel - Schengen visa application for Budapest, Hungary. [3/10] -- Information gathering and correspondance. -- Form filling and preparation supporting documentation. -- Application submission. -- Interview date is on 10th Jan 2017. === Next Week === Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] -- Continue to investigate, possible fix trivial issues and mark rest as xfail with appropriate bug reports. LLDB Arm/AArch64 Investigate and fix testsuite crashes (Pine64 Crashes) [TCWG-792] -- Find a reliable reason to the issue as this hampers our buildbot work. BUD17 Travel - Schengen visa application for Budapest, Hungary. -- Budapest visa interview travelling to Islamabad 9 - 10 Jan 2017.
