rust - What can be the reason of `LLVM ERROR: Target does not support MC emission!`? -

-

I am currently working on Roost in LLVM tutorial. I have already implemented parts of the Kalidoscope REPL. It used to work well for me, but suddenly stopped it to work and LLVM error: every attempt to calculate a value in the target MC does not support emissions it seems now That's it's happy after updating the latest compiler to the latest night (but I'm not sure here).

Follow the relevant piece of code.

Initial function: 

  # [permission (non_snackcase)] Pub unprotected FNLDVMI initiatesNative targets (llvm :: LLVMInitializeX86TargetInfo (); LLVM :: LLVMInitializeX86Target (); LLVM :: LLVMInitializeX86TargetMC (); }   
 Module creation:  
  module = llvm :: LLVMModuleCreateWithNameInContext (module_name.to_c_str). as_ptr (), context);   
 Performance engine creation:  
  let exec_engine = 0 as llvm :: ExecutionEngineRef; Give error = 0 as * const c_char; LLVMCreateExecutionEngineForModule (& amp; Function, Module, and Error;); Insist! (Exec_engine! = Llvm as Ex: = EngineRef Execution);   
 Function compiling and running:  
  Pub FN Run (Value: LLM :: Valerieuf, Context: & amp; Theme) - & gt; F64 {insecure {result = LLVMRunFunction (context.exec_engine; value; 0; 0; const genericValueRef as); Let ty = llvm :: LLVMDoubleTypeInContext (context.context); LLVMGenericValueToFloat (ty, results)}}   
 are imported by LLWM by preflxed LLVM functions :: rustc, which are not prefexed by LLVM :: are imported by my code, see .  
 To see the complete code list,  
 See I am using the latest night of war and LLWM 3.5.0  
 UPD: Launched by LLVMI. After commenting about the call for the Native Targ, GIT started working again. But I am still wondering what is the cause of the problem and how GIT should be used correctly.  
 UPD2: After commenting the line with initialization, everything did not work again: the function in the call defines the code with the  LLVM error: execution of an unknown external function Tried  now  
 The function I am trying to call (previously worked):  
  # [no_mangle] pub extern fn print (x: f64) - & Gt; F64 {println! ("& Gt; {} <", x); X}   
 Example session:  
  jauhien @ zcj iron-copy% ./target/iron_kaleidoscope & gt; Extern print (x) double @ print double) & gt; Print (1) llv error: tried to execute unknown external function: print    
 
 
 I had and could also solve it by turning it on  
  LLVMInitializeNativeAsmPrinter (); LLVMInitializeNativeAsmParser (); After starting X86Target   
 I found it in the source code of  lli .

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
