Hi All, I am trying to build OpenNI drivers and stuck with the following linker error. /usr/bin/ld: error: ../../Bin/Arm-Release/libOpenNI.so uses VFP register arguments, ./Arm-Release/XnBaseNode.o does not /usr/bin/ld: failed to merge target specific data of file ./Arm-Release/XnBaseNode.o /usr/bin/ld: error: ../../Bin/Arm-Release/libOpenNI.so uses VFP register arguments, ./Arm-Release/XnDump.o does not /usr/bin/ld: failed to merge target specific data of file ./Arm-Release/XnDump.o and many more of similar errors with VFP. System : ZYNC ZC702 board with ARM Cortex A9 dual core. OS: Linaro 12.04 LTS GCC - 4.6.3 Is there some flag i have to set in the Makefile to correct the Hard/Soft float type ?

Possible toolchain bug with handling return value of read()

by Riku Voipio

Hi, The testcase at https://launchpadlibrarian.net/128616769/compare-test.c With aarch64: aarch64-oe-linux-gcc -o a-test ./compare-test.c ./a-test: fail ret: -1: Bad address With X86_64: gcc -o test ./compare-test.c ./test correct. ret: -1: Bad address setting -D_FILE_OFFSET_BITS=64 doesn't make a difference. This is with: gcc version 4.7.3 20121205 (prerelease) (Linaro GCC 4.7-2012.12) This was found while debugging: https://bugs.launchpad.net/linaro-aarch64/+bug/1099896 Riku

[Activity] Week 02

by Zhenqiang Chen

Summary: * Rebase and test the shrink-wrap patches. * Learn how branch cost impact on code generation. Details: 1. Rebase and test the shrink-wrap patches. * For pretend arguments, it is hard to generate correct dwarf info for case: * Add dwarf info for ldrd_pop. Testing is ongoing. * Expose an interface from regcpprog and do copy propagation for the entry block. Benchmark logs show there are much more functions can be shrink-wrapped. 2. Read codes and enhance ifcvt.c. * For IF-THEN-ELSE, if the last insn of then_bb or else_bb is ANY_RETURN_P, we can save one JUMP. In this, we'd keep max MAX_CONDITIONAL_EXECUTE, not "max *= 2". A patch is sent out for review. * Take the branch probability into account. Test is ongoing. 3. R/M toolchain related work. Plan: * Follow up the shrink-wrap dwarf info issue. * Investigate benchmarks which is impacted by different branch cost. Planed leaves: * Feb. 9 - 15: Chinese Spring Festival. Best Regards! -Zhenqiang

Help on epilogue dwarf info

by Zhenqiang Chen

Hi, Would you please help on how to generate correct epilogue dwarf info? Without correct dwarf info, when shrink-wrap is enabled, it tends to ICE at dwarf2cfi.c: function maybe_record_trace_start. /* We ought to have the same state incoming to a given trace no matter how we arrive at the trace. Anything else means we've got some kind of optimization error. */ gcc_checking_assert (cfi_row_equal_p (cur_row, ti->beg_row)); Issues: 1) pretend_args The attached pretend_arg.c shows an example about pretend_args dwarf info push {r2, r3} .cfi_def_cfa_offset 8 .cfi_offset 2, -8 .cfi_offset 3, -4 use r3 push {r4, r5, lr} ... pop {r4, r5, lr} add sp, sp, #8 //No instruction here to restore r2 and r3 Can we RESTORE r2 and r3? * If we notes to RESTORE r2 and r3, it might lead to wrong info for GDB since no instruction restores them. * If we do not RESTORE them, the reg_save dwarf info will not be cleared. Then the dwarf check will fail when the function is shrink-wrapped. 2) frame_pointer_needed In prologue, we set fp like fp = sp + INT After this instruction, cfi_def_cfa_register is set to fp In epilogue. we have fp += INT sp = fp Can we reset cfi_def_cfa_register back to sp? * If we set it back to sp, how to handle it in arm_unwind_emit_set, which assumes sp can not be set from other register? /* A stack increment. */ if (GET_CODE (e1) != PLUS || !REG_P (XEXP (e1, 0)) || REGNO (XEXP (e1, 0)) != SP_REGNUM || !CONST_INT_P (XEXP (e1, 1))) abort (); * If we do not set it back, to get correct dwarf info for POP after "sp = fp", we have to add notes " sp = fp + INT" for dwarf-info while we have "sp = sp + INT" in the insn. Here is the workaround POP RTL example for the attached alloca,c: (insn/f 62 61 66 3 (parallel [ (set/f (reg/f:SI 13 sp) // sp = sp + 8 (plus:SI (reg/f:SI 13 sp) (const_int 8 [0x8]))) (set/f (reg:SI 3 r3) (mem/c:SI (reg/f:SI 13 sp) [3 S4 A32])) (set/f (reg/f:SI 7 r7) (mem/c:SI (plus:SI (reg/f:SI 13 sp) (const_int 4 [0x4])) [3 S4 A32])) ]) alloca.c:8 329 {*load_multiple_with_writeback} (expr_list:REG_UNUSED (reg:SI 3 r3) (expr_list:REG_CFA_ADJUST_CFA (set (reg/f:SI 13 sp) (plus:SI (reg/f:SI 7 r7) // sp = fp + 8 (const_int 8 [0x8]))) (expr_list:REG_CFA_RESTORE (reg/f:SI 7 r7) (expr_list:REG_CFA_RESTORE (reg:SI 3 r3) (nil)))))) (3) No idea for if (crtl->calls_eh_return) emit_insn (gen_addsi3 (stack_pointer_rtx, stack_pointer_rtx, gen_rtx_REG (SImode, ARM_EH_STACKADJ_REGNUM))); Currently I have no shrink-wrapped test case which crtl->calls_eh_return is true. Thanks! -Zhenqiang

Instruction costs for ARM/NEON

by Renato Golin

Hi all, I'm helping the loop vectorization in LLVM and for that we need first to build the instruction cost model so we can decide whether the vectorization is worth or not. I was looking at some papers, but most of them concern with energy consumption, which is not the issue (at least not for now). The "cost" model should take the point of view of latency, stalls and pipeline cost. I know there are sporadic comments on this on the ARM ARM, but would be good to have a definite resource where to get the data from (and hope it's a public document). Does anyone know of a good place to start looking for that? Even if the document is private, we can certainly hide the information enough to make it to the LLVM code base. cheers, --renato

compiler crash while building c++ libs

libstdc++6 built from gcc-4.7 missing some symbols for arm-linux-gnueabi

by Matthias Klose

asking for some help about debian #697521 and lp: #1096619. looking at the config.log files for armel/armhf I don't see any differences. I assume it's a difference in the cpu configuration (armv4/v5 vs. armv7) not soft/hard-float. any pointers?

int64_t definition conflict on Aarch64

by Riku Voipio

Hi, The following code fails to build with OE Aarch64 toolchain with current kernel headers. While ugly, the code is a reduced testcase from fuse build failure ( https://bugs.launchpad.net/linaro-oe/+bug/1087757 ) and the same fuse code compiles on all other architectures. Before I send a workaround for upstream, I'd like to know how we can end up with different definitions for int64_t when that happens on no other architectures - something wrong with the generic kernel headers? Testcase: #include <sys/types.h> #define __s64 int64_t #include <signal.h> int main(int argc, char **argv) { int64_t x=4; return x; } Failure: /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc -save-temps --sysroot=/data/oe/build/tmp-eglibc/sysroots/genericarmv8 -o test test.c In file included from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/types.h:7:0, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/types.h:1, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/linux/types.h:4, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/sigcontext.h:19, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/bits/sigcontext.h:27, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/signal.h:338, from test.c:4: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/int-ll64.h:29:44: error: conflicting types for 'int64_t' In file included from test.c:2:0: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/sys/types.h:197:13: note: previous declaration of 'int64_t' was here
