In commit 81502cee20 ("BaseTools/Source/C: take EXTRA_LDFLAGS from the
caller", 2018-08-16), I missed that "VfrCompile/GNUmakefile" does not use
BUILD_LFLAGS in the APPLICATION linking rule, unlike "app.makefile" does.
Instead, "VfrCompile/GNUmakefile" uses the (undefined) LFLAGS macro.
Therefore commit 81502cee20 did not cover the linking step of
VfrCompile.
Thankfully, the structure of the linking rules is the same, between
"app.makefile" and "VfrCompile/GNUmakefile". Rename the undefined LFLAGS
macro in "VfrCompile/GNUmakefile" to VFR_LFLAGS (for consistency with
VFR_CXXFLAGS), and set it to EXTRA_LDFLAGS.
As a result, we have:
| compilation | linking
-----------+--------------------------------+----------------------
VfrCompile | VFR_CXXFLAGS = | VFR_LFLAGS =
| BUILD_OPTFLAGS = | EXTRA_LDFLAGS
| '-O2' + EXTRA_OPTFLAGS |
-----------+--------------------------------+----------------------
other apps | BUILD_CFLAGS/BUILD_CXXFLAGS = | BUILD_LFLAGS =
| [...] + BUILD_OPTFLAGS = | [...] + EXTRA_LDFLAGS
| [...] + '-O2' + EXTRA_OPTFLAGS |
This table shows
- that the VfrCompile compilation and linking flags are always a subset of
the corresponding flags used by the other apps,
- and that the EXTRA flags are always at the end.
