Bug ID: 89659
Summary: [microblaze] unrecognizable insn at floating point
conversion
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ra_gcc_bugzilla at hotmail dot com
Target Milestone: ---
Created attachment 45939

The preprocessed source file
Compiling the attached test case results in an unrecognizable insn internal
compiler error. The test case was reduced from the PARSEC Benchmark Suite,
fluidanimate, pthreads.cpp:344. The compiler used is the one shipped with
Vivado 2018.3, running on Windows 10. -O2 is necessary for the error to occur,
but I was not able to identify the exact optimization flag.
$ mb-gcc -v -save-temps -O2 -mhard-float -mxl-float-convert "test_case.c"
Using built-in specs.
