Small-model C programs compiled with the floating-point emulator
library (/FPi or /FPc option) may produce two segments of code and
data each. If there are floating-point operations in your program, the
compiler will generate these extra segments. The map file shows these
segments as EMULATOR_TEXT and EMULATOR_DATA.

EMULATOR_TEXT is the code segment for the emulator. In some cases,
small-model programs can have two code segments. Because the code in
the emulator only is accessed through far calls and interrupts, this
is not a problem. Both EMULATOR_TEXT and EMULATOR_DATA are in separate
segments from DGROUP and _TEXT in all memory models.
