Diego Novillo 0b8eea8df5 SamplePGO - Sort samples by source location when emitting as text.
When dumping function samples or writing them out as text format, it
helps if the samples are emitted sorted by source location. The sorting
of the maps is a bit slow, so we only do it on demand.

The input gcov file has been generated on a little endian machine. Expect
failures on big endian systems.
XFAIL: powerpc64-, s390x, mips-, mips64-, sparc
Tests for sample profiles encoded in GCC's gcov format.
1- Show all functions. This profile has a single main() function with several
inlined callees.
RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov | FileCheck %s --check-prefix=SHOW1
SHOW1: Function: main: 364084, 0, 6 sampled lines
SHOW1: 2.3: inlined callee: _Z3fool: 243786, 0, 3 sampled lines
SHOW1: 1.3: inlined callee: _Z3bari: 0, 0, 2 sampled lines
SHOW1: 1.7: inlined callee: _Z3bari: 98558, 0, 2 sampled lines
SHOW1: 1.8: inlined callee: _Z3bari: 0, 0, 2 sampled lines
2- Convert the profile to text encoding and check that they are both
identical.
RUN: llvm-profdata merge --sample %p/Inputs/gcc-sample-profile.gcov --text -o - | llvm-profdata show --sample - -o %t-text
RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
RUN: diff %t-text %t-gcov
4- Merge the gcov and text encodings of the profile and check that the
counters have doubled.
RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov %t-gcov -o - | FileCheck %s --check-prefix=MERGE1
