Add outputable instances for the types in GHC.Iface.Ext.Types, add -ddump-hie
flag to dump pretty printed contents of the .hie file
Metric Increase:
hie002
Because of the regression on i386:
compile_time/bytes allocated increased from i386-linux-deb9 baseline @ HEAD~10:
Expected hie002 (normal) compile_time/bytes allocated: 583014888.0 +/-10%
Lower bound hie002 (normal) compile_time/bytes allocated: 524713399
Upper bound hie002 (normal) compile_time/bytes allocated: 641316377
Actual hie002 (normal) compile_time/bytes allocated: 877986292
Deviation hie002 (normal) compile_time/bytes allocated: 50.6 %
*** unexpected stat test failure for hie002(normal)
