8977c0fc78 * TExeSection.Size and .DataPos changed from aword to qword, because:
1) aword follows the ALU size of the CPU, not the address type
  2) MemPos is qword and is already checked against MaxMemPos

677595880a + support for get_frame() for the LLVM target (using the llvm.frameaddress()
intrinsic)

be9d2b1c26 * implement concatcopy for complex types by calling the llvm.memcpy()
intrinsic. This may insert actual calls to a function called memcpy with
    the signature of the libc function, but llvm optimizers are free to
    insert such calls by themselves already. This means that for non-libc
    targets, we will have to add weak symbols for memcpy/memmove/memset
    that call through to move/fillchar when using LLVM, so that these
    implementation are used when not linking to libc

052af9200e * support external declarations for compilerprocs

9ce6e8f801 * Removed the fpmkunit_bootstrap target because it forces building fpmake in
all circumstances which breaks 'make sourcezip'. In fact a revert of
   r29249.

2431b6e63b * i8086-msdos internal linker: use a different approach for finding the stack
