blob: 0165fae7ce234fa649b6ea86cb08d17efa214f3b [file] [log] [blame]
William A. Kennington IIIac69b482021-06-02 12:28:27 -0700[diff] [blame]1We want to pass ${DEBUG_PREFIX_MAP} to gcc commands and also pass in
2 --debug-prefix-map to nasm (we carry a patch to nasm for this). The
3tools definitions file is built by ovmf-native so we need to pass this in
4at target build time when we know the right values so we use the environment.
5
6By using determininistc file paths during the ovmf build, it removes the
7opportunitity for gcc/ld to change the output binaries due to path lengths
8overflowing section sizes and causing small changes in the binary output.
9Previously we relied on the stripped output being the same which isn't always
10the case if the size of the debug symbols varies.
11
12Upstream-Status: Pending [gcc parts may be upstreamable, nasm patch isn't upstream yet]
