Hello Everyone , Please guide me for the following tasks I wish to accomplish by extending C language 1. Add a new keyword "Critical" for integer data type. 2. All the operands in the operations involving such integers will also be marked critical 3. For such operations mainly addition and multiplication , divide the integers into two halves based on their bits , carry out operations on halves separately and combine the result to obtain the original result. Eg, critical int a=5; int b=10; int c=a+b; int d=b*b; c should be calculated as follows: a' and a'' are 16 highest and lowest bits of a respectively. Similarly b' and b'' and c' and c''. so c''=a''+b'' , c'=a'+b'+carry , c=2^16*c'+c''. and d should be calculated normally. Please help me figure which files I need to change to accomplish each of the tasks. Apologies if the tasks are too trivial , I am new to LLVM.
