mjsunit/regress/regress-1122.js triggers immediate field checking failure #33

Closed pengwuibm closed 11 years ago

pengwuibm commented 11 years ago

To reproduce, uncomment out NEW_IMM_CHECK_CODE in src/ppc/assembler-ppc.cc

Running on ppc native:

out/ppc.debug/d8 --test --nocrankshaft --nobreak-on-abort --nodead-code-elimination --enable-slow-asserts --debug-code --verify-heap test/mjsunit/mjsunit.js test/mjsunit/regress/regress-1122.js

val = 40012, 0x9c4c

#

Fatal error in ../src/ppc/assembler-ppc.cc, line 656

CHECK(is_int16(val)) failed

Updated to use new "form-aware" MacroAssembler methods and the test now passes. However there are many more instances of this same problem which we have to decide how to address.
