c++ - How to link one llvm pass to another? -


i have 2 llvm passes. dveloped @ first independent, need combine them , use information 1 of them in another. structure is:

first_pass/

******first_pass.cpp

******cmakelists.txt

second_pass/

******second_pass.cpp

******some_additional_files

******cmakelists.txt

includes/

cmakelists.txt

in common cmakelists file include 2 directories. use class second_pass in first_pass.

two cmakes:

set(cmake_build_type debug)  add_library(mycfgpass module mycfgpass.cpp) #target_link_libraries(mycfgpass llvmpass)  target_compile_features(mycfgpass private cxx_range_for cxx_auto_type) set(cmake_cxx_flags "-fno-rtti") 
set(cmake_build_type debug)  add_definitions(-dtests) add_definitions(-dstats)  add_library( llvmpass module   llvmpass.cpp   info.cpp   printf.cpp   utils.cpp )  target_compile_options(llvmpass public -g3 -o0 -std=c++14 -pedantic -wall) # target_compile_options(llvmpass public -g3 -o0 -std=c++14 -pedantic -wall) set(cmake_cxx_flags "-fno-rtti")

then go error symbol llvmpass undefined. can't link library (llvmpass) because of module type - llvm requires. if create 2 libraries (.so , .a) - registering pass twice. can solution?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
