TODO not working as of 8825222 + 1. Not yet properly researched / reported upstream yet.
Should not be hard in theory since libstdc++ is just part of GCC, as shown at: https://stackoverflow.com/questions/21872229/how-to-edit-and-re-build-the-gcc-libstdc-c-standard-library-source/51946224#51946224
To test it out, I first hack link:common.py[] to enable C++:
consts['baremetal_build_in_exts'] = consts['build_in_exts']
and then I hack link:userland/arch/aarch64/inline_asm/multiline.cpp[] to consist only of an empty main:
then for example:
./build-baremetal --arch aarch64
./run --arch aarch64 --baremetal userland/arch/aarch64/inline_asm/multiline.cpp
fails with:
rom: requested regions overlap (rom dtb. free=0x00000000000000a0, addr=0x0000000000000000)
qemu-system-aarch64: rom check and register reset failed
and the gem5 build fails completely:
./build-baremetal --arch aarch64 --emulator gem5 userland/arch/aarch64/inline_asm/multiline.cpp
fails with:
/tmp/ccFd2YIB.o:(.eh_frame+0x1c): relocation truncated to fit: R_AARCH64_PREL32 against `.text'
