It is impossible to have gcc generate SSE code without it, as thirdparty
applications often call us with an unaligned stack pointer.

Ubuntu 8.10 has llvm-config version 2.2, which doesn't have
nativecodegen. This triggers an exception.

Unfortunately scons does not check if a tool exists before it invokes
its generate function.

gcc-4.2's optimizer has a strange bug where it looses code from inner
loops in certain situations. For example, if the appearently innocent
looking code below is compiled with gcc-4.2 -S -O1, the inner loop's
code is missing from the outputed assembly.
struct Size {
unsigned width;
};
struct Command {
unsigned length;
struct Size sizes[32];
};
extern void emit_command(void *command, unsigned length);
void
create_surface( struct Size size, unsigned faces, unsigned levels)
{
struct Command cmd;
unsigned face;
unsigned level;
cmd.length = faces*levels*sizeof(cmd.sizes[0]);
for(face = 0; face < faces; ++face) {
for(level = 0; level < levels; ++level) {
cmd.sizes[face*levels + level] = size;
// This should generate a shrl statement, but the whole for body
// disappears in gcc-4.2 -O1/-O2/-O3!
size.width >>= 1;
}
}
emit(&cmd, sizeof cmd.length + cmd.length);
}
Note that this is not specific to MinGW's gcc-4.2 crosscompiler (the
version typically found in debian/ubuntu's mingw32 packages). gcc-4.2 on
Linux also displays the same error. gcc-4.3 and above gets this
correctly though.
Updated MinGW debian packages with gcc-4.3 are available from
http://people.freedesktop.org/~jrfonseca/debian/pool/main/m/

This prevents the error
relocation R_X86_64_PC32 against symbol `_gl_DispatchTSD' can not be used when making a shared object; recompile with -fPIC
when building on x86_64 architecture.

Also works with MinGW, as long as the path to the DirectX SDK top
directory is set in the DXSDK_DIR environment variable.

Per Brian's request.
This reverts commit 25f0c33bb3509958a532bdd72b3945c1d5d1cad5.

Match what autotools and other build systems do by default.

MSVC 64bit compiler takes forever on some of the files.
Might want to revisit this again later.

You can still get the old behavior by passing the option quiet=no to scons.

Have to use LINK /LIB instead. The biggest problem is when the command
line is very long and all the options are included in a argument file --
link doesn't like if /LIB is included in the argument file.

x86_64 is also supported.

Mingw gdb apparently chokes on dwarf debug info.

DRI drivers can be build side by side with other non-DRI drivers, therefore
there is no need to build gallium twice.
|

Like ccache, but works on all OSes.

It creates problems in many libraries (glut, glew) which are not unicode
aware.
|
|
It a scary world out there: people use all sort of non standard C stuff,
and we must enable support for that in here in order to build.
-pedantic still warn us when we use that nonstandard though.

This allows to build MinGW and MSVC within the same dir.
