Hi , This is regrading ,with below commit Revision 256571 - (view) (download) - [select for diffs] Modified Tue Dec 29 12:18:07 2015 CST (5 months ago) by mcrosier File length: 35649 byte(s) Diff to previous 254562 (colored) Add command line options to force function/loop alignments. These are being added for testing purposes. http://reviews.llvm.org/D15648 How do we enable/disable above

Hi Justin , Thank you for the confirmation and we would like to know that ,going forward the clang has the support the gcc gcov format or use the -fprofile-instr-generate -fcoverage-mapping and get ride of gcov format . We are planing to customize the clang code coverage for embedded world ,before we start tweaking the gcov / -fprofile-instr-generate code-base ,we would like to take feedback

Hi Everyone, How do we particular disable optimization in llvm with -O2 enabled? for example "Interprocedural Sparse Conditional Constant Propagation" Thank you ~Umesh -------------- next part -------------- An HTML attachment was scrubbed...

Hi Guys , Did clang has the support for ILP32 data model on the ARM target like aarch64 /arm64 ? Thank you ~Umesh

Hi All , I'm not sure the question is relevant to the forum,My apologies if not We are trying to instrument our code with ASan(Clang) to find the memory errors and we see that the application execution halts when the Asan check finds the memory issue at the being. Which mean we need to fix the issue then compile and execute the instrumented code again to find the next issue and so on

Hi Guys , We are trying to enable LTO on our code base for clang(3.8) using gold linker , and we are stuck with below error bash-4.1$ /arm-install/bin/armeb-linux-gnueabi-ld.gold --be8 /arm-install/bin/armeb-linux-gnueabi-ld.gold: --be8: unknown option And found that ,Be8 (byte invariant addressing) is not supported in the gold linker, Questions is ,how do we go from here ? Do be8

Dear All, Attached files is related to the changes made to add the Schedmodel for a AMD bulldozer target, Please note that , the model is incomplete but has some of the valuables features implemented. Request to the group or someone from AMD for the comments on the implementation. Thanks ~umesh On Wed, Nov 13, 2013 at 8:14 PM, Umesh Kalappa <umesh.kalappa0 at gmail.com>wrote: >

Hi andrea, R11 treated as frame pointer at arm backend , which is fixed again .

Try using $PWD/test.cpp on the clang command line.

Hi All, We have populated info in the Clang Sema i.e class Sema (include/clang/Sema/Sema.h) and like to propagate the same to Clang Codegen . Currently we are propagating through ASTContext ,where we have duplicating fields info and operation in the Sema and ASTContext . Any better way of doing the same ? Thank you ~Umesh

Or should I use the latest llvm SVN trunk instead? I wrote it on trunk, but I expect it to be fairly easy to port on 3.8. This is really just quickly plumbing an option on the TargetMachine creation. --
