Change error to warning when a profile cannot be found. When the profile for a function cannot be applied, we use to emit an error. This seems extreme. The compiler can continue, it's just that the optimization opportunities won't include profile information. llvm-svn: 220386

Use discriminator information in sample profiles. Summary: When the sample profiles include discriminator information, use the discriminator values to distinguish instruction weights in different basic blocks. This modifies the BodySamples mapping to map <line, discriminator> pairs to weights. Instructions on the same line but different blocks, will use different discriminator values. This, in turn, means that the blocks may have different weights. Other changes in this patch: - Add tests for positive values of line offset, discriminator and samples. - Change data types from uint32_t to unsigned and int and do additional validation.

Tolerate unmangled names in sample profiles. Summary: The compiler does not always generate linkage names. If a function has been inlined and its body elided, its linkage name may not be generated. When the binary executes, the profiler will use its unmangled name when attributing samples. This results in unmangled names in the input profile. We are currently failing hard when this happens. However, in this case all that happens is that we fail to attribute samples to the inlined function. While this means fewer optimization opportunities, it should not cause a compilation failure. This patch accepts all valid function names, regardless of whether they were mangled or not.

[llvm-profdata] Add check for text profile formats and improve error reporting (2nd try) Summary: This change addresses two possible instances of user error / confusion when merging sampled profile data. Previously any input that didn't match the raw or processed instrumented format would automatically be interpreted as instrumented profile text format data. No error would be reported during the merge. Example: If foo-sampled.profdata and bar-sampled.profdata are binary sampled profiles: Old behavior: $ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -output foobar-sampled.profdata $ llvm-profdata show -sample foobar-sampled.profdata error: foobar-sampled.profdata:1: Expected 'mangled_name:NUM:NUM', found lprofi This change adds basic checks for valid input data when assuming text input. It also makes error messages related to file format validity more specific about the assumbed profile data type. New behavior: $ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -o foobar-sampled.profdata error: foo.profdata: Unrecognized instrumentation profile encoding format Perhaps you forgot to use the -sample option?

Use DiagnosticInfo facility. Summary: The sample profiler pass emits several error messages. Instead of just aborting the compiler with report_fatal_error, we can emit better messages using DiagnosticInfo. This adds a new sub-class of DiagnosticInfo to handle the sample profiler.
