A system that generates a per user abstraction of a store from a connection point. Filtering a view set of a hierarchically secured containment hierarchy based on the access permissions of the principal is one of the novel features of the invention. The invention can offer a collection of primitives that can operate on this aggregation that span multiple container hierarchies with potentially heterogeneous security descriptors. The model can reduce the necessity to traverse the container hierarchy to discover all the accessible items in a domain.

A program or program snippet is rewritten to conform to site-specific properties prior to being executed by a target host. The program or program snippet directed to a target host from a known or unknown source is either intercepted by a server before reaching the target host or can be redirected from the target host to the server to effect its rewriting. The program is parsed in its external representation, converting it to an internal representation that is inspected and analyzed with reference to a site-specific properties database. A summary of the program's properties is then compared to the site-specific properties database by a binary rewriting engine, which produces a rewritten program in an internal representation. If appropriate, the program or program snippet is rewritten to convert it to a format suitable for execution on the target host. Furthermore, certifications may be added to the rewritten program to mark that the rewritten program obeys site-specific constraints. The rewriting service thus produces a program in an appropriate target representation that conforms to site-specific properties. These properties may relate to security, auditing, optimization, monitoring, threading, and / or management of the rewritten program.

A method for translating instructions for a processor. The method includes accessing a plurality of guest instructions that comprise multiple guest branch instructions, and assembling the plurality of guest instructions into a guest instruction block. The guest instruction block is converted into a corresponding native conversion block. The native conversion block is stored into a native cache. A mapping of the guest instruction block to corresponding native conversion block is stored in a conversion look aside buffer. Upon a subsequent request for a guest instruction, the conversion look aside buffer is indexed to determine whether a hit occurred, wherein the mapping indicates whether the guest instruction has a corresponding converted native instruction in the native cache. The converted native instruction is forwarded for execution in response to the hit.

A sequence of input language (IL) instructions of a guest system is converted, for example by binary translation, into a corresponding sequence of output language (OL) instructions of a host system, which executes the OL instructions. In order to determine the return address after any IL call to a subroutine at a target entry address P, the corresponding OL return address is stored in an array at a location determined by an index calculated as a function of P. After completion of execution of the OL translation of the IL subroutine, execution is transferred to the address stored in the array at the location where the OL return address was previously stored. A confirm instruction block is included in each OL call site to determine whether the transfer was to the correct or incorrect call site, and a back-up routine is included to handle the cases of incorrect call sites.

A system and method for converting byte code of a first type into byte code of a second type. Byte code of a first type is received as input. The first byte code is converted into constituent byte code data elements that can comprise any logical unit or grouping of at least a portion of a software application. The first byte code data elements are mapped to data elements of a second byte code type. The second byte code data elements are assembled into a resulting second byte code.

Methods and apparatus are disclosed for fusing instructions to provide OR-test and AND-test functionality on multiple test sources. Some embodiments include fetching instructions, said instructions including a first instruction specifying a first operand destination, a second instruction specifying a second operand source, and a third instruction specifying a branch condition. A portion of the plurality of instructions are fused into a single micro-operation, the portion including both the first and second instructions if said first operand destination and said second operand source are the same, and said branch condition is dependent upon the second instruction. Some embodiments generate a novel test instruction dynamically by fusing one logical instruction with a prior-art test instruction. Other embodiments generate the novel test instruction through a just-in-time compiler. Some embodiments also fuse the novel test instruction with a subsequent conditional branch instruction, and perform a branch according to how the condition flag is set.

According to one embodiment, a binary code modification system includes a code modifier configured to access a binary software code. The code modifier generates a modified software code by inserting one or more executable instructions into the binary software code. The one or more executable instructions is operable to provide identity and access management (IAM) functionality or governance functionality to the modified software code.

A method and system of generating target applications from Java reference applications for a particular combination of mobile devices is provided. The method includes the steps of: a) unpacking the reference application into a number of class files; and b) transforming the reference application into the target application by a plug-in. The plug-in is capable of transforming different reference applications into corresponding target applications for a particular combination of the reference mobile device and the target mobile device. The system includes a transformation engine and a plug-in corresponding to the reference / target mobile device combination. The plug-in includes an XML file and pieces of software code to modify corresponding portions of the reference application not supported by the target mobile device. The XML file directs the transformation engine to identify the unsupported portion of the reference application and to modify the portion with the selected software code.
