| 项目描述: |
Version 2.0 of the Itanium Architecture Dependency Violation Checking Library made the following improvements to Version 1.0:
Implemented the new dependence semantic "stop" (DCO 511): a branch predicated with p63 and a subsequent mod-sched-br must be separated by a 'stop' .
Two bugs were fixed - relevant to abstract mode only! Both are in the API DVLoc_validateAbstrInstr, used to check the correctness of an abstract instruction:
The first bug incorrectly produced an DVLOC_ERR_WRONG_OPERANDS error on floating point load pair instructions (ldfp...).
The second bug incorrectly produced an DVLOC_ERR_WRONG_OPERANDS error on the following instructions:
mov pr = r2,mask17
mov pr.rot = imm44
mov r1 = pr
mov itr.d dtr[r3] = r2
2.0版本的Itanium Architecture Dependency Violation Checking Library对1.0版本进行了如下改进：
实现了新的依赖语义"stop" (DCO 511):使用p63 谓词会出现分歧，必须用'stop' 来分离一个mod-sched-br 子序列。
修复了两个错误－只与抽象模型相关！都是在DVLoc_validateAbstrInstr API中的错误，用于检查抽象指令的正确性：第一个错误是由于浮点运算加载对指令(ldfp...)引起的 DVLOC_ERR_WRONG_OPERANDS 错误。第二个错误是由于使用下列指令而引起的一个DVLOC_ERR_WRONG_OPERANDS错误：mov pr = r2,mask17
mov pr.rot = imm44
mov r1 = pr
mov itr.d dtr[r3] = r2
