Bug ID: 148908
Summary: Simplify JIT::emit_op_mod()
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: sukolsak at gmail.com
The IDIV instruction on x86 divides the value in the EDX:EAX registers by the source operand and stores the quotient in EAX and the remainder in EDX. Therefore, we store the values that we don't want to be overwritten by IDIV in registers that are not EAX or EDX. This patch makes the intention clearer and makes the code easier to read.
