Hi, My first post in this group, so I hope it's the correct one. I'm using a MIPS32 base processor (4KSd) which also has the MIPS16e extensions. First of all, some of the default compiler flags I have use the -mips16e compiler flag, even though I can only find the -mips16 (so without the 'e') flag in the GNU GCC documentation online. (http://gcc.gnu.org/onlinedocs/gcc-4.4.4/gcc/MIPS-Options.html#MIPS-Options). I can not find any -mips16e specific documentation.) So for my project, I use both the -mips23r2 and -mips16e compiler flags. Some of my files (startup files) contain assembly code, and do not get compiled with the above settings (it does not recognize 'di' 'sync' and 'ei' as valid opcodes). These opcodes exist in the MIPS32r2 instruction set, but not in the MIPS16e extensions. My assumption was that using the -mips16e compiler flag, would only enable the use of the mips16e specific extensions, but it seems like it will only use the compact instruction set? Can I use -mips16e and -mips32r2 simultaneously, or does it force the compiler to ONLY use the compact instruction set? Thanks Johan Schuld
