The libgc source is distributed here as an amalgamation (https://sqlite.org/amalgamation.html).
|
|
This means that, rather than mirroring the entire bdwgc repo here, the amalgamate tool
|
|
was used to bundle all C files and local includes together into a single C file, which is
|
|
much easier to handle. This helps keep the V source distribution small, can reduce compile
|
|
times by 3%-15%, and can help C compilers generate more optimized code.
|
|
|
|
For generating the libgc amalgamation, the following commands were used:
|
|
|
|
git clone https://github.com/ivmai/bdwgc.git
|
|
cd bdwgc
|
|
./autogen.sh
|
|
./configure --enable-threads=pthreads \
|
|
--enable-static \
|
|
--enable-shared=no \
|
|
--enable-thread-local-alloc=no \
|
|
--enable-parallel-mark \
|
|
--enable-single-obj-compilation \
|
|
--enable-gc-debug
|
|
|
|
../../../cmd/tools/amalgamate -o ../gc.c \
|
|
-b atomic_ops.h \
|
|
-b gc/gc.h \
|
|
-b gc/gc_backptr.h \
|
|
-b gc/gc_disclaim.h \
|
|
-b gc/gc_gcj.h \
|
|
-b gc/gc_inline.h \
|
|
-b gc/gc_mark.h \
|
|
-b gc/gc_pthread_redirects.h \
|
|
-b gc/gc_tiny_fl.h \
|
|
-b gc/gc_typed.h \
|
|
-b gc/javaxfc.h \
|
|
-b il/PCR_IL.h \
|

-b mm/PCR_MM.h \
|
|
-b psp2-support.h \
|
|
-b stubinfo.h \
|

-b th/PCR_ThCtl.h \
|
|
-b vd/PCR_VD.h \
|
|

|
|
-s include/private \

|
|
|
|
The updated header files are then copied into the include/gc directory. We can delete
|
|
include/gc/gc_cpp.h since this header is not needed by V. And, we can remove the git
|
|
repo for bdwgc.
|
|
|
|
cp include/gc/*.h ../include/gc
|
|
cd ..
|
|
rm include/gc/gc_cpp.h
|
|
rm -rf bdwgc
|
