i need a crosscompiler to be configured from the GCC compiler as in our new project we cant use Compiler provided by TI ( as it will have optimizations ) which will affect our compliance , So i need to configure a cross compiler from GCC compiler using Cygwin ( i am using TM4C129ENCPDT , its bareboard , the compiler will run on my windows 10 PC ). does anyone of you have any experience on this or can any one guide me or suggest me a place where i can get data related to this .
