##
## The following variables can be customized at build time. Use env or export to change at your wish
##
##   Example: env enable_pgo=y makepkg -sc
##
## Optimized build: env enable_pgo=y enable_lto=y makepkg -sc
## Optimized build, less RAM required: env enable_pgo=y enable_lto=y enable_no_keep_memory=y makepkg -sc
## Less optimization enabled, faster compilation: env enable_pgo=n enable_lto=n makepkg -sc
##
## Enable PGO, increasing performances but makes the compilation slower.
## It builds Firefox a first time without LTO, runs the test suite to generate
## a PGO profile, then builds Firefox again (with optional LTO) using this
## profile.
## Set variable "enable_pgo" to: y to enable (increase performance, default in official firefox-beta)
##                               n to disable  (less optimized, but faster compilation, as it will skip the profile generation)
if [ -z ${enable_pgo+x} ]; then
  enable_pgo=y
fi

## Enable LTO, increasing performances but makes the compilation slower and
## requires more RAM to build. Only affects clang, rust has LTO enabled by
## default.
## Disable it if the compilation runs out-of-memory.
## Set variable "enable_lto" to: y to enable (increase performance, default in official firefox-beta, but slower to compile)
##                               n to disable  (less optimized, but faster to compile)
if [ -z ${enable_lto+x} ]; then
  enable_lto=y
fi

## Enable --no-keep-memory in LD when compiling with LTO enabled. Useful when
## running OOM during the compilation, as LD will consume less memory when ##
## linking. Doesn't impact the performance of the generated binary, but makes
## the compilation a bit slower.
## Set variable "enable_no_keep_memory" to: n to disable  (default)
##                                          y to enable (slower compilation, but compilation requires less memory)
if [ -z ${enable_no_keep_memory+x} ]; then
  enable_no_keep_memory=n
fi
