let t : Char[buffer.num-items]

Howto compile herschel code to binary
2+
-------------------------------------
3+
4+
1. Add llvm tools into the path.
5+
6+
2. You need the little runtime addition rt.c, precompile it with clang or gcc
7+
8+
3.
9+
../temp/debug/hrc -c -s compile/d.hea ; llc d.ll ; gcc -o d.out d.s rt.o
10+
11+
and this is even faster:
12+
13+
../temp/debug/hrc -c -b compile/d.hea ; llvm-ld -v -native -o d3.out d.bc rt.o

Requirements
2+
3+
for the code itself:
4+
- c and c++ (tested with gcc 4.0.1 and 4.2.1 on Mac OS X, 4.5.0 on
5+
mingw/linux; clang 2.8 on Mac OS X)
6+
- llvm 2.9 (http://www.llvm.org)
7+
8+
for building and testing:
9+
- a shell (posix compliant shell)
10+
- sed
11+
- GNU make (tested with GNU make 3.81)
12+
- python (tested with python 2.5.1)
13+
14+
for the documentation:
15+
- texinfo (the makefile refers to texi2pdf and makeinfo). For the PDF
16+
documentation you need a substantial tex installation
17+
18+
19+
Developed on Mac OS X (10.5 and 10.6), Linux, and Windows XP.
20+
21+
22+
Build on Unix (incl. Mac OS X):
23+
24+
1. build llvm (e.g. in ~/tmp/llvm-build)
25+
26+
$ mkdir $TMP_DIR/llvm-build
27+
$ cd $TMP_DIR/llvm-build
28+
$ $LLVM_SRC_ROOT/configure
29+
$ make
30+
31+
or just get a precompiled binary from the llvm site (if available) and
32+
install it whereever you prefer.
33+
34+
2. run the configure script from within the build directory. Herschel
35+
can be build in a separate build directory:
36+
37+
$ cd my-build
38+
$ ../herschel/configure
39+
40+
See the "--help" option to that script to check different
41+
configuration possibilities. If you have llvm installed in a location
42+
which is not in your search path (esp. the "llvm-config" tool) you
43+
have to specify this information with the "--with-llvm-config" option:
44+
45+
$ ./configure --with-llvm-config=~/Dev/llvm-build2.8/Release/bin/llvm-config
46+
47+
3. review the settings in $HERSCHEL_ROOT/config.mk; probably create a
48+
config-local.mk and overwrite settings there.
49+
50+
4. go to $HERSCHEL_ROOT and type 'make'
51+
52+
$ make
53+
54+
This should build the compiler, runtime libraries, prepare the
55+
documentation, and runs the unit tests (if configured so). To run the
56+
complete test suite type
57+
58+
$ make tests
59+
60+
from the toplevel development folder. To create the documentation type
61+
62+
$ make docs.
63+
64+
If everything went smooth you can find the created tools and
65+
documentation in the 'temp' folder.
66+
67+
5. Install: TBD
68+
69+
70+
Build on Windows XP:
71+
72+
- only tested with mingw32. You need at least version
73+
mingw-get-inst-20100909, i.e. gcc 4.5.0. gcc 4.4.0 shows some strange
74+
inconsistency in the default c++ library setup.
