ICE-testcase-gcc-10.2.0.tar.gz
ICE-testcase-gcc-10.2.0.tar.gz contains two object files that seems to be
enough to feed into gcc-10.2.0 to get IRA crash. Unfortunately it's not a
source-based example. Is it useful to get the idea where ira goes wrong?
I hope it's a simple(ish) bug in not traversing some subset of CFG.

My interpretation of the above: under some circumstances (different profile
data?) gcc generates two variants of specialised form of
BitwiseCast<double,unsigned long>:
1. VIEW_CONVERT_EXPR form
2. and 'call BitwiseCast (const double aFrom, long unsigned int * aResult)'
form
Once LTO merges both definitions somehow one of them becomes unreachable for
initial part of register allocator (initial analysis?) but not later phase
(actual register allocation?). And assertion fails.

Thank you for the report. I can reproduce it but it would be handy to provide a
pre-processed source files (-E option) for the 2 objects.

So it's pretty clear what happens, it's about mixing of different flags:
TestFloatingPoint.o:
'-fno-openmp' '-fno-openacc' '-mtune=generic' '-march=x86-64' '-O3' '-O0'
'-Wno-error=maybe-uninitialized' '-Wno-error=deprecated-declarations'
'-Wno-error=array-bounds' '-Wno-error=coverage-mismatch'
'-Wno-error=free-nonheap-object' '-Wno-error=class-memaccess'
'-Wno-error=deprecated-copy' '-Wno-error=shadow' '-flto' '-flifetime-dse=1'
'-fstack-protector-strong' '-fPIC' '-fno-strict-aliasing' '-ffunction-sections'
'-fdata-sections' '-fno-exceptions' '-fno-math-errno' '-fomit-frame-pointer'
'-funwind-tables'
while Unified_cpp_mfbt0.o:
'-fno-openmp' '-fno-openacc' '-mtune=generic' '-march=x86-64' '-O3'
'-Wno-error=maybe-uninitialized' '-Wno-error=deprecated-declarations'
'-Wno-error=array-bounds' '-Wno-error=coverage-mismatch'
'-Wno-error=free-nonheap-object' '-Wno-error=class-memaccess'
'-Wno-error=deprecated-copy' '-flto' '-flifetime-dse=1'
'-fstack-protector-strong' '-fPIC' '-fno-strict-aliasing' '-ffunction-sections'
'-fdata-sections' '-fno-exceptions' '-fno-math-errno' '-fomit-frame-pointer'
'-funwind-tables' '-fprofile-use' '-fprofile-correction'
the profiles are merged in ipa_merge_profiles where match=false due to a
different CFG and we forget to drop back dst->count. I'll prepare a patch for
it.
