Dear Sir,
I would like to use m68k-elf-gprof, so I pass -pg flag to m68k-elf-gcc.
m68k-elf-gcc -mcpu=5282 -O3
-TD:/BuildTools/CodeSourcery_4_2/m68k-elf/lib/m5282evb-ram-hosted.ld
sort.c -o sort -pg
and I have the error
C:\DOCUME~1\tungpham\LOCALS~1\Temp/ccYfcaaa.o: In function `main':
sort.c:(.text+0x16): undefined reference to `mcount'
profiling relies on an mcount function, and is not supported on an ELF toolchain
