Hi,
I always thought that Qemu never has C++ code inside, but I am surprise to see this when Aarch64 emulator is linked, as following (excerpt)
c++ -I/usr/include/pixman-1 -I/home/me/projects/qemu-2.3.0/dtc/libfdt -fPIE -DPIE -m64 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wstrict-prototypes -Wredundant-decls -Wall -Wundef -Wwrite-strings -Wmissing-prototypes -fno-strict-aliasing -fno-common -Wendif-labels -Wmissing-include-dirs -Wempty-body -Wnested-externs -Wformat-security -Wformat-y2k -Winit-self -Wignored-qualifiers -Wold-style-declaration -Wold-style-definition -Wtype-limits -fstack-protector-all -I../linux-headers -I.. -I/home/me/projects/qemu-2.3.0/target-arm -DNEED_CPU_H -I/home/me/projects/qemu-2.3.0/include -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -pthread -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -g -Wl,--warn-common -Wl,-z,relro -Wl,-z,now -pie -m64 -g -o qemu-system-aarch64 exec.o translate-all.o cpu-exec.o ...
A question: is there any reason to use C++ for linker here? Why does C linker not work?
Thanks.
