Hi Guys, I am writing a GIMPLE pass in which I need to inspect the assignments. For example, for the below statements, I need to find the value of the second and third assignments which are '2' and '7'. VAR1 = 1; VAR1++; VAR1 = VAR1 + 5; But the GIMPLE IR only has the following statements i.e. no optimization. VAR1_2 = 1; VAR1_3 = VAR1_2 + 1; VAR1_4 = VAR1_3 + 5; How can I make it perform calculations on RHS? Are there some flags that I can enable? I tried -O1 and higher optimization levels but I don't see any difference. This is how I am building and loading my plugin... g++ -I`g++ -print-file-name=plugin`/include -fPIC -shared -O1 gimple_pass.c -o plugin.so g++ -fplugin=/home/sandeep/myplugin/gimple/plugin.so -O1 -c test.c Also, I thought of going with RTL passes but RTL IR seems too complex for my use and also it's not suitable for high level optimizations. Please suggest. Thanks and regards, Sandeep.
