Hello, This might be a non standard usage, so please bear with me. I am in the process of writing a tool. The idea is that the user puts comments at certain points of his program. The comments have specific keywords. Once the code is compiled to generate assembly code, I would like to parse through the assembled code and then extract certain information based on the comments inserted in the code. The second part of the application is when the same process is followed to extract information from the linker output. For example, I would like to extract the physical address from which the current instruction is being executed. Can someone point me in the right direction if GCC has support to preserve the comments in the code as it assembles and links the code? Thanks in advance ... -- View this message in context: http://old.nabble.com/preserving-comments-tp30296498p30296498.html Sent from the gcc - Help mailing list archive at Nabble.com.
