## edd 29 Nov 2001	Default to g++

## edd 14 Jan 2003	no longer change g++ as g++-3.2 is now default
# 			but use g++-3.0 on ia64
#ifneq "$(findstring $(arch), ia64)" ""
#cxxcompiler	= g++-3.0
#endif

## edd 01 Feb 2002  	allow -ffunction-sections on hppa
## edd 26 Oct 2007      turn strict aliasing warning off
## edd 01 May 2011      add -fpermissive as g++ is more of a stickler
## edd 06 May 2011      remove -fpermissive with QL 1.1 betas
## edd 09 Sep 2018      bringing over a few extra settings for hppa
#compilerflags	= -O2 -Wall -Wno-strict-aliasing -DBOOST_NO_AUTO_PTR
## edd 07 Aug 2019      turning optimisation off or else linking (with lto) fails

#cxxcompiler	= g++-3.0
endif

## edd 18 May 2002	no optimisation or debugging on baby systems
## edd 14 May 2005	don't do it on mipsel or mips either
## edd 01 Jun 2007      no longer activate this on mips/mipsel
## edd 26 Jun 2007 	use cpu test, not arch test -- thanks to Riku via #430709
## edd 26 Oct 2007      s390+powerpc also die, so add'em (and remove mips(el), see next item)
## edd 27 May 2012      added mips/mipsel/armel/armhf here too
## edd 11 Mar 2015      remove powerpc and armhf from the list as they built on Ubuntu (cf
##                      https://launchpad.net/ubuntu/+source/quantlib-swig/1.5-1ubuntu1) and #779720)
##                      also remove mips, mipsel as they are getting taken care of below

ifneq "$(findstring $(cpu), m68k arm armeb s390 armel)" ""
compilerflags   = -O0 -g0 -DBOOST_NO_AUTO_PTR
endif

## edd 26 Oct 2007      really reset mips/mips to -O2 (see #419742)
## edd 27 May 2012      move to previos section
## edd 06 Dec 2014      patch by Dejan Latinovic (see #772028) to add -mxgot
## edd 23 Jun 2016      patch by Daniel Knezevic (see #827979) to add gcc-min-expand=20
## edd 29 Sep 2018      adding mips64el here as well as it recently timed out
ifneq "$(findstring $(cpu), mipsel mips mips64el)" ""
#compilerflags   = -O2 -g0
compilerflags   = -O0 -g0 -mxgot --param ggc-min-expand=20 -DBOOST_NO_AUTO_PTR
endif

## edd 21 Aug 2018      i386 now seems to be hosted on amd64
ifneq "$(findstring $(arch), i386)" ""
compilerflags   = -O0 -g0 --param ggc-min-expand=20 -DBOOST_NO_AUTO_PTR
endif

## edd 22 Aug 2018      trying to help a few other systems with their memory exhaustion
ifneq "$(findstring $(cpu), hurd-i386 kfreebsd-i386 m68k powerpc x32)" ""
compilerflags   = -O0 -g0 --param ggc-min-expand=20 -DBOOST_NO_AUTO_PTR

## edd 25 Dec 2002  g++-3.2 for s390
