The target would be arm-freebsd, since armhf is not treated as a separate CPU by FPC. You need to create arm startup files in the rtl/freebsd/arm folder.Yes, I know. But to add this new CPU support for the FPC/FreeBSD, it is better I start with files of rtl/freebsd/i386 or rtl/freebsd/x86_64 or use another start point, like rtl/netbsd/arm ?
The primary goal of a startup code is to get pointers to the command line parameters and the environment block. If arm-freebsd uses the stack to pass these pointers (the same way as i386-freebsd), then you need just to convert the i386 startup assembly to the arm assembly.
For start you need only the prt0.as file. Yuriy. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
