Joel Dice	24f682f5b6	fix 64-bit shifts on x86_32 (part 2) ... My earlier attempt (fa5d76b) missed an important detail, and somehow I forgot to test the 32-bit OpenJDK build which made that omission obvious. Here's the fix.	2012-09-03 08:44:13 -06:00
Joel Dice	fa5d76b43e	fix 64-bit shifts on x86_32	2012-08-13 08:26:39 -06:00
Joel Dice	69ffa28e1b	fix shift instruction implementations on ARM ... Unlike x86, ARM does not implicitly mask the shift value, so we must do so explicitly.	2012-08-11 19:09:03 +00:00
Joel Dice	71295e54c7	handle constants larger than 8 bits in subtractBorrowCR	2012-03-11 04:59:42 -06:00
Joel Dice	be01e5b687	fix handling of 64-bit arguments to Method.invoke on 32-bit architectures ... The previous code failed to account for alignment padding in the Double and Long classes.	2011-09-12 20:26:32 -06:00
Joel Dice	7bea2b6b7d	fix putstatic/putfield for 64-bit volatiles ... We must call acquireMonitorForObject before popping the putstatic/pushfield operands off the stack to avoid clobbering said operands.	2011-05-23 12:38:12 -06:00
Joel Dice	857dcd13e7	fix 64-bit constant comparisons on 32-bit platforms	2010-12-20 18:08:52 -07:00
Joel Dice	1d9489a76e	fix a couple of 64-bit-op-on-32-bit-system bugs ... We weren't properly handling the case where a 64-bit value is multipled with itself in multiplyRR, leading to wrong code. Also, addCarryCR didn't know how to handle constants more than 8-bits wide.	2010-11-30 16:58:51 -07:00
Joel Dice	19dca18cd0	disable Math.abs(long) intrinsic on 32-bit x86 ... It never worked and caused the compiler to crash instead due to an impossible-to-fulfill constraint.	2010-11-30 11:36:18 -07:00
Joel Dice	ddc90ef76e	fix 64-bit left shifts with constant shifts greater than or equal to 32 ... The shiftLeftC function in powerpc.cpp was miscompiling such shifts, leading to crashes due to illegal instructions and other weirdness due to instructions that meant something completely different. This commit fixes that and adds a test to Longs.java to make sure it stays fixed.	2010-07-23 10:52:58 -06:00
Joel Dice	935329d7cf	fix 32-bit shift case in unsignedShiftRightC	2009-08-11 12:36:25 -06:00
