LLVM Language Reference Manual LLVM 6 documentation. This document is a reference manual for the LLVM assembly language. LLVM. is a Static Single Assignment SSA based representation that provides. It is the common code. LLVM compilation. Msp430 Example Programs In CMsp430 Example Programs For RetirementThe LLVM code representation is designed to be used in three different. IR, as an on disk bitcode representation. Msp430 Example Programs In JavascriptJust In Time compiler, and as a human. This allows LLVM to provide a. The three different forms of LLVM are. This document describes the human readable. The LLVM representation aims to be light weight and low level while. It aims to be. a universal IR of sorts, by being at a low enough level that. IRs, allowing many source languages to. By providing type information, LLVM can be used as. C automatic variable is never accessed outside of. Msp430 Example Programs In PythonSSA value. instead of a memory location. It is important to note that this document describes well formed LLVM. There is a difference between what the parser accepts. For example, the following. The. LLVM infrastructure provides a verification pass that may be used to. LLVM module is well formed. This pass is automatically. Msp430 Example Programs Of ArrayReference Home. Corrections, suggestions, and new documentation should be posted to the Forum. The text of the Arduino reference is licensed under a Creative Commons. The MSP430 is a mixedsignal microcontroller family from Texas Instruments. Built around a 16bit CPU, the MSP430 is designed for low cost and, specifically, low. The American Radio Relay League ARRL is the national association for amateur radio, connecting hams around the U. S. with news, information and resources. The violations pointed out by the verifier. LLVM identifiers come in two basic types global and local. Global. identifiers functions, global variables begin with the. Local identifiers register names, types begin with the. Additionally, there are three different formats for. Named values are represented as a string of characters with their. For example, foo, Division. Demo Overview. This demo allows users to evaluate TIs CC256x Bluetooth device by using the PAN1323EMK kit and the MSPEXP430F5438 board. The CC256xMSP430 Bluetooth. Code Composer Studio v7. x for MSP430 Users Guide Literature Number SLAU157AO May 2005Revised May 2017. Msp430 Example Programs Of JavaMsp430 Example Programs Of TurboBy. Zero. a. really. The actual regular expression used is. A Z. a z. A Z. 0 9. Identifiers that require other. Special. characters may be escaped using xx where xx is the ASCII. In this way, any character can. The 0. 1 prefix. Unnamed values are represented as an unsigned numeric value with. For example, 1. 2, 2, 4. Constants, which are described in the section Constants below. LLVM requires that values start with a prefix for two reasons Compilers. Additionally, unnamed identifiers allow a compiler to quickly come up. Reserved words in LLVM are very similar to reserved words in other. There are keywords for different opcodes add. These reserved words cannot conflict. Here is an example of LLVM code to multiply the integer variable. X by 8 The easy way After strength reduction And the hard way 0addi. X,X yields i. 32 01addi. This last way of multiplying X by 8 illustrates several important. LLVM Comments are delimited with a and go until the end of line. Unnamed temporaries are created when the result of a computation is. Unnamed temporaries are numbered sequentially using a per function. Note that basic blocks and unnamed. For example, if the. It also shows a convention that we follow in this document. When. demonstrating instructions, we will follow an instruction with a comment. LLVM programs are composed of Modules, each of which is a. Each module consists of. Modules may be. combined together with the LLVM linker, which merges function and. Here is an example of the hello world module Declare the string constant as a global constant. A0. 0 External declaration of the puts functiondeclarei. Definition of main functiondefinei. Convert 1. 3 x i. Call puts function to write out the string to stdout. Named metadata 0i. This example is made up of a global variable named. In general, a module is made up of a list of global values where both. Global values are. All Global Variables and Functions have one of the following types of. Global values with private linkage are only directly. In particular, linking. Because the. symbol is private to the module, all references can be updated. This. doesnt show up in any symbol table in the object file. Similar to private, but the value shows as a local symbol. STBLOCAL in the case of ELF in the object file. This. corresponds to the notion of the static keyword in C. Globals with availableexternally linkage are never emitted into. LLVM module. From the linkers. They exist to allow inlining and other. Globals. with availableexternally linkage are allowed to be discarded at. This linkage type is. Globals with linkonce linkage are merged with other globals of. This can be used to implement. Unreferenced linkonce globals are allowed to be discarded. Note. that linkonce linkage does not actually allow the optimizer to. To enable inlining and other optimizations, use. This is used for globals that are declared weak. C source code. commoncommon linkage is most similar to weak linkage, but they. C, such as int. X at. Symbols with common linkage are merged in the. Functions and aliases may not have. When two global variables with appending. This is the LLVM, typesafe, equivalent of having the. Unfortunately this doesnt correspond to any feature in. The semantics of this linkage follow the ELF object file model the. Some languages allow differing globals to be merged, such as two. Other languages, such as. C, ensure that only equivalent globals are ever merged the. ODR. Such languages can use the. These linkage. types are otherwise the same as their non odr versions. If none of the above identifiers are used, the global is externally. It is illegal for a function declaration to have any linkage type. LLVM functions, calls and. The calling convention of any pair of dynamic. The following calling conventions are supported by LLVM, and more may be. The C calling convention. This calling convention the default if no other calling convention. C calling conventions. This calling. convention supports varargs function calls and tolerates some. C. fastcc The fast calling convention. This calling convention attempts to make calls as fast as possible. This calling convention. ABI Application Binary Interface. Tail calls can only. GHC or the Hi. PE convention is. This calling convention does not. The cold calling convention. This calling convention attempts to make code in the caller as. As such, these calls often preserve all registers. This calling convention does not support varargs and requires the. Furthermore the inliner doesnt consider such function. GHC convention. This calling convention has been implemented specifically for use by. Glasgow Haskell Compiler GHC. It passes everything in registers, going to extremes to achieve this. This calling convention should. At the. moment only X8. On X8. 6 3. 2 only supports up to 4 bit type parameters. No. floating point types are supported. On X8. 6 6. 4 only supports up to 1. This calling convention supports tail call. The Hi. PE calling convention. This calling convention has been implemented specifically for use by. High Performance Erlang. Hi. PE compiler, the. Ericssons Open Source ErlangOTP. It uses more. registers for argument passing than the ordinary C calling. The calling. convention properly supports tail call. It uses a register pinning. GHCs convention, for keeping frequently. At the moment only X8. Web. Kits Java. Script calling convention. This calling convention has been implemented for Web. Kit FTL JIT. It passes arguments on the. Dynamic calling convention for code patching. This is a special convention that supports patching an arbitrary code. This convention forces the call. This can currently only be used with calls to. See Stack maps and patch points in LLVM. preservemostcc The Preserve. Most calling convention. This calling convention attempts to make the code in the caller as. This convention behaves identically to the C. This alleviates the. If the arguments are passed in callee saved registers.
