[LLVMdev] llvm-config --cxxflags is not consistent when building by cmake.
Hi,
We found `llvm-config --cxxflags' does not have -fno-exceptions -fno-rtti
when using cmake to build LLVM.
Does anyone know how to fix it?

[LLVMdev] llvm-config --cxxflags does not give the result the configuration script wants?
...k I found a bug in llvm's CMakeLists.(I use llvm 3.1svn and
Clang 3.1) I follow the normal way to try to compile an application that
utilize both clang and llvm: I ./autogen.sh it, ./configure it and make it.
But the make fails. At last I found out the failure is because that the
Makefile's CXXFLAGS does not contain -fno-rtti option which is needed by
the compilation.
The "configure" file of the application use llvm-config --cxxflags to
assign to the CXXFLAGS. But Although I see that, under my platform, almost
all the the files inside LLVM and Clang are compiled with -fno-rtti, the...

[LLVMdev] Why does `llvm-config --cxxflags` now include -fno-rtti ?
Hi,
I'm trying to port a piece of code using LLVM as a library to the
latest SVN version.
One difference between 2.6 and 2.7svn is that `llvm-config --cxxflags`
now include -fno-rtti. Since my code does use RTTI information (in
non-trivial dynamic_cast), my code can't compile with this. Same goes
for -fexceptions.
I've tried setting my CXXFLAGS to `llvm-config --cxxflags` -frtti
-fexceptions, now my code compiles, but it doesn't link against...

As these two are no longer GCC "specific" we can move them out of the if

PKG_CFLAGS/CFLAGS and PKG_CXXFLAGS/CXXFLAGS
...what you didn't want: -O2.
In R-exts, it says that "Flags which are set in file etc/Makeconf can
be overridden by the environment variable MAKEFLAGS (at least for
systems using GNU make), as in (Bourne shell syntax)" but this
doesn't work if I set either MAKEFLAGS or CFLAGS/CXXFLAGS in my
configure.ac script or package Makevars.
Does anyone have any ideas on how to reliably override the default
CFLAGS/CXXFLAGS given in Makeconf?
Many thanks,
Ernest

[LLVMdev] [PATCH 0/2 v3] add visibility hidden to tls entry points
Patch 1 adds a check for the compilers visibility macro to configure.ac.
Patch 2 avoids redefined symbol errors in clang of the tls entry points.
Based on a suggestion from Rafael Ávila de Espíndola <rafael.espindola at gmail.com>
in http://llvm.org/bugs/show_bug.cgi?id=19778.
Tested with gcc 4.9 and clang 3.6(rc)

Default R-3.4.0 RC CXXFLAGS without -O2 on x86_64-linux-gnu with g++-5.4.0 causes WARNING from stl_list.h

problem customizing CXXFLAGS in Windows
...shared library in Windows with customized level of optimization.
Specifically, I would like to have "-O3 -funroll-loops" as flags when I run
"R CMD SHLIB ***.cc" to speed the program for my simulations.
I have read through the documentation and have tried adding the line
PKG_CXXFLAGS = -O3 -funroll-loops
in my Makevars in my package's src directory. However, this places the
flags before the -O2 flag, thereby overriding it. I have also tried
creating a config.site file in R_HOME/etc, but that seems to be ignored.
I found a possible solution at

Using -fno-rtti and -fno-exceptions is an internal LLVM policy. There is
no reason to impose it on client code.

difference between install from source and install from repositories
Hi,
What is the difference between the R installation from source and the R
installation from ubuntu repositories. Specifically when I install
R-3.1.1 on ubuntu 14.04 from sources ldflags and CXXFLAGS are different
that those from the installation from a repo.
Installation from sources:
R CMD config --ldflags
-Wl,--export-dynamic -fopenmp -L/home/prana/prana_R/third-party/install/lib/R/lib -lR -lrt -ldl -lm
R CMD config CXXFLAGS

replace -Wextra with -W
The attached small configury patch replaces -Wextra with -W in the
main CFLAGS and CXXFLAGS assignments. A few lines after them, -Wextra
is conditionally added already with XIPH_ADD_CFLAGS([-Wextra]), so
this allows build using older compilers.
Regards.
