1370 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1371 # But there are times where we need a bit more control. The motivating
1372 # and currently only case is Android: this is almost identical to
1373 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1374 # platform variant tags, which get passed in the compile as
1375 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1376 #
1377 # In almost all cases, the <variant> bit is "vanilla". But for Android
1378 # it is "android" instead.

1381 #
1382 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla

1384 # whilst an Android build would have
1385 #
1386 # -DVGP_arm_linux -DVGPV_arm_linux_android

2991 #
2992 # For GNU (bfd) ld -Ttext-segment chooses the base at which ELF headers
2993 # will reside. -Ttext aligns just the .text section start (but not any
2994 # other section).
2995 #
2996 # LLVM ld.lld 10.0 changed the semantics of its -Ttext. See "Breaking changes"
2997 # in https://releases.llvm.org/10.0.0/tools/lld/docs/ReleaseNotes.html
2998 # The --image-base option (since version 6.0?) provides the semantics needed.
2999 # -Ttext-segment generates an error, but -Ttext now more closely
3000 # follows the GNU (bfd) ld's -Ttext.
3001 #
3002 # So test first for --image-base support, and if that fails then
3003 # for -Ttext-segment which is supported by all bfd ld versions
3004 # and use that if it exists. If it doesn't exist it must be an older
3005 # version of gold and we can fall back to using -Ttext which has the
3006 # right semantics.

5027 # of the regtest programs that use Boost fails, because they are
5028 # build as 32-bit (IN THIS EXAMPLE).
