similar to: [LLVMdev] Integer ID for LLVM::Instruction*?

David, As you suggested, I try to compile the following test code: *include "llvm/IR/Instruction.h"#include "stdint.h"extern void callback(intptr_t);void foo(){ llvm::Instruction* i; intptr_t zzzz=static_cast<intptr_t>(i); callback(zzzz);}* but got this compilation error: * 'intptr_t' (aka 'long') is not allowed intptr_t

Hi, Are there some built-in LLVM transformation pass, or written library code that transforms LLVM::SwitchInst into if-condition statements (LLVM:: BranchInst)? The purpose of the transformation is that we have a legacy program analyzer that includes an LLVM pass manipulating if-condition statements. Statements of LLVM::SwithchInst should have been handled in the same manner but was not done.

Hi, I have a naive question on how to generate LLVM IR for inline functions. I have compiled this C code: *inline void func1()* * {* * int x=3;* * }* * void func2()* * {* * func1();* * int y = 4;* * }* into LLVM IR, using clang -emit-llvm -S -c <filename> But the generated LLVM IR file does *not* have func1() expanded (see below for the relevant parts). *; Function Attrs: nounwind

Hello, I am looking for a loop unfolding procedure implemented in LLVM that helps to transform a while-loop to n-layer If-statements. The transformation should be on IR, although the example below is illustrated on the source level. original loop: * WHILE (condition) DO action ENDWHILE* Expected unfolded loop (2-layer): * IF (condition) THEN* * action* * IF

Thank you, kcc. I am unsure if I misunderstand your reply. It seems that trace-bb, rather than trace-pc, fits better for my problem, given that my instrumentation is to put before each conditional statement. Do I misunderstand something here? " Tracing basic blocks <http://clang.llvm.org/docs/SanitizerCoverage.html#id11> With -fsanitize-coverage=trace-bb the compiler will insert

Hi, I am using LLVM to develop a tool, using Mac OS 10.9. I have download llvm source and binary from http://llvm.org/releases/download.html I just find the BasicBlock.h file of the binary package clang+llvm-3.6.0-x86_64-apple-darwin/include/llvm/IR/BasicBlock.h is slightly different from that of the source llvm/include/llvm/IR/BasicBlock.h In particular, llvm:: getModule(..)

I do agree that sign-extension is the right thing to do. Unlike bit-fields, llvm::PointerIntPair has asserts checking that the int value is within range. So if you assign an out of range value, it should fail with an assertion: llvm::PointerIntPair<SomeType*, 3, int> pip; pip.setInt(7); // can be made to fail as the valid range // of signed 3-bit values is [-4:3] The above

Hi, all I want to instrument a program automatically so that it prints "hello" before each conditional statement. For example, consider the function P below. int P(int x) { if (x<3) if (x>0) return 1; return 0; } Let P_instrum be the instrumented version of P. It is expected that: -- P_instrum(1) prints two "hello"s --

Greetings, all. I've got a datafile I've been working with that has an ideosyncratic, heterogeneous format. It's grossly like: [...] DISKREAD,metadata about disks MEM,metadata about memory ZZZZ,observation-identifier,time,date DISKREAD,observation-identifier,data about disks MEM,observation-identifier,data about memory [ and repeat for each observation ] What I've done in

Each register is a 4-component (namely, r, g, b, a) vector register. They are actually defined as llvm packed [4xfloat]. The instruction: add_sat r0.a, r1_bias.xxyy, r3_x2.zzzz Explaination: '.a' is a writemask. only the specified component will be update '.xxyy' and '.zzzz' are swizzle masks, specify the component permutation, simliar to the Intel SSE permutation

Actually the problems that Tzu-Chien Chiu are encountering are similar to what should be done for generating SSE code in the X86 backend and also other SIMD instruction sets. I think LLVM neeeds to add instructions for permuting components, extracting and injecting elements in packed types. If the architecture has instructions which can do permutations for each instruction (for example

Hi, I have 2 Debian testing boxes running a very similar setup (both running the latest aptosid kernel); on one of them, since the iptables/libxtables10 packages have been upgraded from 1.4.19.1-1 to 1.4.20-2, shorewall-init can''t start shorewall anymore and for this reason ifupdown also fails triggering firewall up. Shorewall can be successfully started later on, and ifupdown starts

Can someone explain to me what is happening here: ~ $ touch foo ~ $ ln foo bar ~ $ ls foo bar bar foo ~ $ mv foo bar ~ $ ls foo bar bar foo I try to move a file over a hard linked copy of itself and the move fails, but there is no error. Is this the intended behavior? -- Ben Escoto

Hi Zhoulai, I am trying to modify "LoopUnrollPass" in llvm which produces multiple copies of loop equal to the loop unroll factor.Currently, using multicore architecture, say 3 for example and the execution goes like: for 3 cores if there are 9 iterations of loop core instruction 1 0,3,6 2 1,4,7 3 2,5,8 But I want to to

Hello list! I have mongrel service 0.1.0 working on my current production machine. Upgrading to a new server and also moving to mongrel service 0.3.1 has not worked yet. I am hoping someone will have an idea as to why.

When recording inbound agent calls, if the queues use agent members (Agent/6000), we can get the calls recorded as agent-xxxx.yyyy.zzzz.gsm where xxxx is the agent number. However, if the queues use phone members (SIP/6000), the recorded filename is simply yyyy.zzzz.gsm. Is there any way of making the recorded file either agent-xxxx or even sip-xxxx where xxxx is the extension number. I had
