Bug #: 54269
Summary: [4.8 Regression] memory usage too large when
optimizing
Classification: Unclassified
Product: gcc

Severity: normal
Priority: P3
Component: rtl-optimization
AssignedTo: [email protected]

gzipped testcase.
The attached testcase requires +- 10Gb resident memory to compile with:
gfortran -c -O3 -funroll-all-loops -march=native -ffree-form -D__LIBINT
hfx_contraction_methods.F
using current trunk. I believe this is a recent regression in trunk. 4.7 needs
500Mb. From a very quick gdb session, I guess this is some rtl thing.
