--- Comment #2 from Don <clugd...@yahoo.com.au> 2011-08-23 01:52:36 PDT --- Thanks bearophile, that reduction is very helpful. The code loads 8 values on the x87 stack. The eighth one would cause an overflow, so in cg87.c, push87(), it inserts: fdecstp; fstp [EBP - 24]; The next line is: fld [EBP - 18]; The code passes to the scheduler, where there's a bug: it converts the code to: fdecstp; fld [EBP - 18]; fxch ST(1); fstp [EBP - 24]; This is an x87 stack overflow, since the load happens before space has been made in the save. The x87 returns a NaN. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
