Am there a defined Macro for Compiler and uController being used?

I'm coming from another uC family and only starting with MCUXpresso for the OM13085 LPC1769,


I use my own libraries of C Source code for various families and compile code using compiler switches and uC switches. Are there such things for the LPC1769.


Copying the line from the build in MCUXpresso I've got a uC of __LPC17XX which is not as specific as I'd like for source code. I'm sure there are probably differences between various members of the LPC17XX family, even if it is the number of Hardware timers etc. So I only want to try writing code for TIMER_5 if I'm on LPC17AB, for example. And I can't see a compiler defined, it's obviously the arm-none-eabi-gcc but there is no -D__ARM_NONE_EABI_GCC in the command line. that's the kind of info I'll need in source as different compilers have subtle differences.
