This introduces support for a new toolchain GCC5 which is identical to GCC49, except for the fact that it enables LTO for X64 and AARCH64.
In order to allow the same FAMILY and BUILDRULEFAMILY to be reused, a shell script is used that translates LD arguments to GCC arguments on the fly. I.e., most -xxx arguments are translated to their -Wl,xxx pass throught equivalent, and some other arguments are interpreted by the script directly. Using the same FAMILY and BUILDRULEFAMILY is important, since many .DSC and .INF files contain [BuildOptions] sections that set DLINK flags for, e.g., all GCC/X64 targets, and so using GCC as the linker instead of LD (which LTO requires) would either require a complete new toolchain FAMILY (which would make the GCC5 unavailable without changes to many packages, including out of tree ones), or a new BUILDRULEFAMILY, which has similar problems. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <[email protected]> --- Again, this is not an attempt to interfere with the great work Steven is doing. I am simply concerned that adding a new FAMILY or BUILDRULEFAMILY for GCC in LTO mode further fragments the support for GCC, which is already difficult to maintain. For example, packages that set BuildOptions only for the GCC/LTO FAMILY could not be built with GCC4x without changes. The use of a shell script is a hack, and to support this approach for GCC on Windows, we should probably change it to a shell script. We may even add BaseTools support for converting a LD command line string to a GCC one directly. The point of this RFC is to illustrate is that such translation is feasible, and avoids the pitfall of having to introduce a new FAMILY or BUILDRULEFAMILY I have included LTO support for AARCH64 as well to illustrate that the same approach works there too. Note that the resulting build is BROKEN, i.e., LTO for AARCH64 does not actually work at the moment, but this is under investigation.
