I am adding the tests that Jakub mentioned as a runtime performance regression tests.

Bug ID: 80249
Summary: Failed to build SPEC 2006 483.xalancbmk with
-fdump-tree-fre
Product: gcc
Version: 7.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization

Reduced testcase
An ICE occurs while building 483.xalancbmk in SPEC2006 with the flag
-fdump-tree-fre (while compiling TokenFactory.cpp)
The attached test case has been reduced from it. It fails with both x86-64 and
AArch64 with the following command :
g++ -O3 -fdump-tree-fre reduced.cpp
reduced.cpp: In member function 'xercesc_2_5::Token*
xercesc_2_5::TokenFactory::getGraphemePattern()':
