2017-08-31Revert r312240Alex Lorenz
The buildbots have shown that -Wstrict-prototypes behaves differently in GCC and Clang so we should keep it disabled until Clang follows GCC's behaviour git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@312246 91177308-0d34-0410-b5e6-96231b3b80d8

2016-02-26[profile] Compute number of data entries correctlyVedant Kumar
Compiler-rt miscalculates the number of entries in the __llvm_prf_data section on i386 Darwin. This results in a number of test failures (which we started catching after r261344). The fix we attempted earlier is insufficient (r261683). It caused some tests to start passing again, but that hid the fact that we drop some data entries. This patch should fix the real problem. It fixes the way we compute DataSize by taking into account the way the Darwin linker lays out __llvm_prf_data.

2015-10-16Use struct type instead of raw array for raw profile header (NFC)Xinliang David Li
This patch introduces a well defined header struct to represent raw profile header instead of using raw array. Previously the raw array is used in two different files and is very error prone when header structure is re-organized. This is a small cleanup with NFC. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@250561 91177308-0d34-0410-b5e6-96231b3b80d8
2015-07-09Add support for generating profiles in a given directory.Diego Novillo
When the file is initialized, this patch checks whether the path specifies a directory. If so, it creates the directory tree before truncating the file.

2015-04-28This change is the first of 3 patches to add support for specifyingEric Christopher
the profile output from the command line via -fprofile-instr-generate=<path>, where the specified output path/file will be overridden by the LLVM_PROFILE_FILE environment variable. Several changes are made to the runtime to support this: Add a new interface __llvm_profile_override_default_filename that will set the profile output filename, but allows LLVM_PROFILE_FILE to override. This is the interface used by the new option. Refactor the pid-expansion done for LLVM_PROFILE_FILE into a separate routine that can be shared by the various filename setting routines (so that the filename from the option can also use the "%p" syntax). Move the truncation into setFilename, and only truncate if there is a new filename specified (to maintain support for appending to the same profile file in the case of multiple shared objects built with profiling). Move the handling for a NULL filename passed to __llvm_profile_set_filename and __llvm_profile_override_default_filename into the new setFilenamePossiblyWithPid routine. This now correctly resets the output file to default.profraw instead of NULL. The handling for a null LLVM_PROFILE_FILE (which should not reset) is done by caller setFilenameFromEnvironment.

2014-12-09profile: Add low level versions of profile buffer functionsJustin Bogner
On Darwin, compiler_rt uses magic linker symbols to find the profile counters in the __DATA segment. This is a reasonable method for normal, hosted, userspace programs. However programs with custom memory layouts, such as the kernel, will need to tell compiler_rt explicitly where to find these sections. Patch by Lawrence D'Anna. Thanks! git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@223840 91177308-0d34-0410-b5e6-96231b3b80d8
2014-09-04profile: Avoid name collisions between instrumentation and runtimeJustin Bogner
The naming scheme we're using for counters in profile data shares a prefix with some fixed names we use for the runtime, notably __llvm_profile_data_begin and _end. Embarrassingly, this means a function called begin() can't be instrumented. This modifies the runtime names so as not to collide with the instrumentation. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@217166 91177308-0d34-0410-b5e6-96231b3b80d8
2014-05-17InstrProf: Support profiling dlopen'd shared librariesDuncan P. N. Exon Smith
Shared objects are hard. After this commit, we do the right thing when profiling two separate shared objects that have been dlopen'd with `RTLD_LOCAL`, when the main executable is *not* being profiled. This mainly simplifies the writer logic. - At initialization, determine the output filename and truncate the file. Depending on whether shared objects can see each other, this may happen multiple times. - At exit, each executable writes its own profile in append mode. <rdar://problem/16918688> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209053 91177308-0d34-0410-b5e6-96231b3b80d8

Change the API of the instrumented profiling library to work with shared objects. - Most things are now declared hidden, so that each executable gets its own copy. - Initialization hooks up a linked list of writers. - The raw format with shared objects that are profiled consists of a concatenated series of profiles. llvm-profdata knows how to deal with that since r208938. <rdar://problem/16918688> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@208940 91177308-0d34-0410-b5e6-96231b3b80d8
