In commit 81502cee20ac ("BaseTools/Source/C: take EXTRA_LDFLAGS from the
|
|
|
cc9195 |
caller", 2018-08-16), I missed that "VfrCompile/GNUmakefile" does not use
|
|
|
cc9195 |
BUILD_LFLAGS in the APPLICATION linking rule, unlike "app.makefile" does.
|
|
|
cc9195 |
Instead, "VfrCompile/GNUmakefile" uses the (undefined) LFLAGS macro.
|
|
|
cc9195 |
Therefore commit 81502cee20ac did not cover the linking step of
|
|
|
cc9195 |
VfrCompile.
|
|
|
cc9195 |
|
|
|
cc9195 |
Thankfully, the structure of the linking rules is the same, between
|
|
|
cc9195 |
"app.makefile" and "VfrCompile/GNUmakefile". Rename the undefined LFLAGS
|
|
|
cc9195 |
macro in "VfrCompile/GNUmakefile" to VFR_LFLAGS (for consistency with
|
|
|
cc9195 |
VFR_CXXFLAGS), and set it to EXTRA_LDFLAGS.
|
|
|
cc9195 |
|
|
|
cc9195 |
As a result, we have:
|
|
|
cc9195 |

|
|
cc9195 |
| compilation | linking

|
|

This table shows
|
|
|
cc9195 |
- that the VfrCompile compilation and linking flags are always a subset of
|
|
|
cc9195 |
the corresponding flags used by the other apps,
|
|
|
cc9195 |
- and that the EXTRA flags are always at the end.
