2020-04-05Fix hard-coded path to DTC that breaks packaging (#428)Joel Sherrill1-1/+1
configure.ac included code which detects and inserted a full path to dtc. Unfortunately, when building with a packaging system, this path reflects the path under a staged building area. Also the inclusion of a full path breaks the use case where someone keeps two versions of dtc on their computer and sets their PATH to switch between them. spike will continue to use the one on their PATH when it was built rather than the intended one.

2020-03-03Allow overriding CFLAGS and similar when buildingRupert Swarbrick1-3/+4
Before this patch, I don't think it was possible to change (say) CFLAGS as part of running the make command. Nor did setting them when running configure do anything. Getting this right is a little fiddly: for example, see Automake's approach at [1] ("AM_CFLAGS" and friends). This patch adds an "mcppbs-" prefix, and sets things up properly for CFLAGS, CPPFLAGS, CXXFLAGS and LDFLAGS. Note that the bulk of the patch is either the auto-generated configure script or the ax_*.m4 files vendored in from the autoconf archive (needed to handle --export-dynamic correctly without trashing settings from the user running configure). What's supposed to happen is as follows: - Base compilation flags that should apply to everything (standard optimisation flags, warning flags etc.) are defined in Makefile.in. - When the user runs configure, they can set compilation flags on the command line. These end up as environment variables in the shell script. - Compilation flags that can only be decided when we run configure (this is currently just whether we support -Wl,--export-dynamic) are appended to the configure-time LDFLAGS environment variable. - At the end of the configure script, these environment variables are spliced into Makefile.in to fill out the corresponding @<varname>@ entries. - When running make, the user might again override compilation flags. These will get appended to the flags found so far. As a concrete example: mkdir build cd build ../configure CXXFLAGS='-O3' make CXXFLAGS='-O0' will result in c++ compile commands that look like this: g++ -MMD -MP \ -DPREFIX=\"/usr/local\" -Wall -Wno-unused -g -O2 -std=c++11 \ -O3 \ -O0 \ -I. -I.. -I../fesvr -I../riscv -I../dummy_rocc -I../softfloat \ -I../spike_main -fPIC -c ../fesvr/elfloader.cc (I've added some newlines to wrap the long line). Note that we have the base flags from Makefile.in (called $(default-CXXFLAGS) there) first. Then we have the -O3 from the configure command. Finally we have the -O0 from the Make command line. And I can finally run "make CXXFLAGS='-O0 -g3'". Phew! [1] https://www.gnu.org/software/automake/manual/html_node/Flag-Variables-Ordering.html

2015-05-13Install pkg-config files for SpikePalmer Dabbelt1-0/+6
The actual Spike package consists of a whole bunch of libraries. This installs a pkg-config file for each generated library, and a meta pkg-config file (riscv-spike.pc) that links in all the other Spike libraries except dummy_rocc (which I figure isn't interesting). This allows me to package and install spike, and then use that package to build an extension library (so I don't have to fork Spike for my own ISA extension).
