4 day work week (03-Apr good Friday) (2/10) * ASAN 32bit allocator failures on amd-01 (4/10) Completed analyzing failures. Sent a patch to Address sanitizes community for review. Applied patch to latest LLVM trunk and ran tests. found one failure. But it was due to the test case assuming that return value from "getpwnam_r" all is always zero. Fixed the test case by removing the assert and all LLVM tests passes. [ Renato tested the patch on APM (39 bit VA) ]. * Again there is some discussion in GCC bugzilla on deciding which allocators to use for Aarch64 42 bit VA*. I have a patches for both allocators and posted it to ASAN group 64 bit allocators wont work on juno. So for ASAN there is a need to have some kind of dynamic address space detection mechanism. Set the allocators type and required mappings at runtime for Aarch64. But that needs to be decided by ASAN group whether to do that or use my 32 bit allocator patch . I am planning to stop it here and wait as suggested by renato. * Get TSAN building for Aarch64 on 42-bit VMA systems. (2/10) (-pie mode only) Applied patch that I had on GCC tree on LLVM trunk. Build failed need to set kVdsoBeg and kMadviseRangeBeg. I set some default value to allow TSAN build to complete. right now clang does not recognize aarch64 target for aarch64 although I enabled it under TSAN. looking at the issue. * Emails, meetings. (2/10) * Linaro 1-1 with christophe, Ryan, status meet * AMD meetings/event, 1-1 with AMD manager, status meeting. * GCC mailing list. == Plan == * Get TSAN building for Aarch64 on 42-bit VMA systems. (-pie mode only) * Document TSAN/ASAN work and patch details in wiki. == Issues == * ASAN patch cannot be up streamed unless we decide on allocator to use.

-O2 faster than -O3

by Edward Nevill

Hi, I did some tests on the following function --- CUT HERE --- int fibo(int n) { if (n < 2) return 1; return (fibo(n-2) + fibo(n-1)); } --- CUT HERE --- and I discovered that it is faster -O2 than -O3. This is with gcc 4.9.2. Looking at the disassembly I see it is using FP registers to hold integer values. The following is a small extract. .L3: fmov w0, s8 sub w25, w25, #1 cmn w25, #1 add w0, w0, w27 fmov s8, w0 bne .L19 add w0, w0, 1 b .L2 Recompiling with -mgeneral-regs-only generates a huge improvement. The following are the times I get on various partner HW. I have normalised the -O2 times to 1 second so that I do not disclose actual partner performance data: Partner 1: -O2 = 1sec, -O3 = 1.13sec, -O3 -mgeneral-regs-only = 0.72sec Partner 2: -O2 = 1sec, -O3 = 0.68sec, -O3 -mgeneral-regs-only = 0.60sec Partner 3: -O2 = 1sec, -O3 = 0.73sec, -O3 -mgeneral-regs-only = 0.68sec Partner 4: -O2 = 1sec, -O3 = 0.83sec, -O3 -mgeneral-regs-only = 0.84sec So, in general, -O3 does actually do better than -O2, but in all cases performance is better if I stop it using FP registers for int values. I have put a tarball of the test program along with 3 binaries and 3 disassemblies here:- http://people.linaro.org/~edward.nevill/fibo.tar All the best, Ed.

* ASAN/TSAN run on 42 bit VA Aarch64 (TCWG-634) (6/10) Sent a patch that enables ASAN tests with 64 bit allocator on amd-01 (AMD Seattle). All ASAN test passes in LLVM. But on juno platform 39 bit VA does not have enough memory to map hence we need to stay on 32 bit allocator. Discussed with ASAN community and it is been decided to use 32 bit allocator as default. They are not ok with having a mechanism to detect VA and swutch allocators based on that. Started looking at failures on amd-01 (AMD steatle) with 32 bit alloctor. None of the ASAN tests ran when I switched to 32 bit allocator on amd-01. Reason there is a spin mutex lock which is waiting for the memory allocation to complete, but assertion failure makes it to wait infinitely. After fixing map range the assertion failure is gone but I keep getting some failures with 32 bit allocator "on". Bug869: Continued to look at ABS_EXPR cases (2/10). * Emails, meetings. (2/10) * Linaro 1-1 with christophe, Ryan, status meet * AMD meetings/event, 1-1 with AMD manager, status meeting. * GCC mailing list. == Plan == *Continue to fix TSAN/ASAN 32bit allocator failures on amd-01 . * Bug869

Interesting changes in this GCC source package release include * Linaro bugzilla PR fixed : #902 * Updates to GCC 4.9.3-pre+svn219502 * Backport of [AArch64] Support SISD variants of SCVTF,UCVTF * Backport of [AArch64] Fix ICE in aarch64_float_const_representable_p * Backport of [AArch64] Switch to sched-pressure by default. * Backport of [AArch64] Add scheduler for ThunderX * Backport of [AArch64] Remove crypto extension from default for cortex-a53, cortex-a57 * Backport of [AArch64] doloop pattern for -fmodulo-sched * Backport of [AArch32] Add execution tests of ARM REV intrinsics. * Backport of [AArch32] Post-indexed addressing for NEON memory access * Backport of [AArch32] Improve 64 bit division performance (serie) * Backport of [AArch32] Revert 215321 backport. * Backport of [AArch32/AArch64] Add ACLE 2.0 predefined macros * Backport of PR tree-optimization/54742 - extend jump thread for finite state automata * Backport of PR target/61997 - cc1plus ICE with aarch64 target using PCH and builtin functions * Backport of PR target/63724 - Fix up BSL expander for floating point types * Backport of [LRA] Relax one gcc_assert in lra-eliminate for fixed register * Backport of Add clobber_reg function Feedback and Support Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. ** Linaro Toolchain Development "mailing list": http://lists.linaro.org/mailman/listinfo/linaro-toolchain ** Linaro Toolchain IRC channel on irc.freenode.net at @#linaro-tcwg@ * Bug reports should be filed in bugzilla against GCC product: http://bugs.linaro.org/enter_bug.cgi?product=GCC * Interested in commercial support? inquire at "Linaro support":mailto: support(a)linaro.org [1] Stable source package releases are defined as releases where the full Linaro Toolchain validation plan is executed. [2] Engineering source package releases are defined as releases where the compiler is only put through unit-testing and full validation is not performed.
