The following files might still have some slightly different (L)GPL copyright notice because they were derived from other programs: - files under coregrind/m_demangle which come from libiberty: cplus-dem.c, d-demangle.c, demangle.h, rust-demangle.c, safe-ctype.c and safe-ctype.h - coregrind/m_demangle/dyn-string.[hc] derived from GCC. - coregrind/m_demangle/ansidecl.h derived from glibc. - VEX files for FMA detived from glibc: host_generic_maddf.h and host_generic_maddf.c - files under coregrin/m_debuginfo derived from LZO: lzoconf.h, lzodefs.h, minilzo-inl.c and minilzo.h - files under coregrind/m_gdbserver detived from GDB: gdb/signals.h, inferiors.c, regcache.c, regcache.h, regdef.h, remote-utils.c, server.c, server.h, signals.c, target.c, target.h and utils.c Plus the following test files: - none/tests/ppc32/testVMX.c derived from testVMX. - ppc tests derived from QEMU: jm-insns.c, ppc64_helpers.h and test_isa_3_0.c - tests derived from bzip2 (with embedded GPL text in code): hackedbz2.c, origin5-bz2.c, varinfo6.c - tests detived from glibc: str_tester.c, pth_atfork1.c - test detived from GCC libgomp: tc17_sembar.c - performance tests derived from bzip2 or tinycc (with embedded GPL text in code): bz2.c, test_input_for_tinycc.c and tinycc.c
