So that it can be renamed to _glapi_get_dispatch.
|
|
In bridge mode, mapi no longer implements glapi.h. It becomes a user of
glapi.h. Imagine an app that uses both libGL.so and libGLESv2.so.
There will be two copies of glapi in the app's memory. It is possible
that _glapi_get_dispatch does not return what _glapi_set_dispatch set,
if they access different copies of the global variables. The solution
to this situation to build either one of the libraries as a bridge to
the other. Or build both libraries as bridges to another shared
glapi library.
|
|
When MAPI_MODE_GLAPI is defined, u_current_table is renamed to
_glapi_Dispatch or _glapi_tls_Dispatch. The ASM dispatchers should not
use hardcoded name.
|
|
The new implementation is based on mapi. No new script is needed. As
noted in sources.mk, the way to use it is to compile MAPI_GLAPI_SOURCES
with MAPI_MODE_GLAPI defined.
|
|
Fix GLAPIPrinter, ES1APIPrinter, and ES2APIPrinter to output files that
are ready for compilation. Since gl_and_es_API.xml is based on
gl_API.xml, the hidden and handcode attributes of entries have to be
overridden for ES1APIPrinter and ES2APIPrinter.
|
|
Treat prefix as macro when it is all uppercase. Generate PREFIX(name)
instead of PREFIXname when it is a macro.
|
|
A prerequisite if we want to convert vgapi.csv to vgapi.xml, or to use
mapi for glapi.
|
|
|
|
Make it clear that entry.h does not depend on stub.h.
|
|
Since struct mapi_table is opaque, MAPI_TMP_DEFINES is not needed in
table.h.
|
|
Given a dispatch slot, entry_get_public returns the address of the
corresponding public entry point. There may be more than one of them.
But since they are all equivalent, it is fine to return any one of them.
With entry_get_public, the address of any public entry point can be
calculated at runtime when an assembly dispatcher is used. There is no
need to have a mapping table in such case. This omits the unnecessary
relocations from the binary.
|
|
Add accessors for struct mapi_stub and make it opaque.
|
|
For example, a printer may ask not to output noop dispatch table.
|
|
Hidden entries are just like normal entries except that they are not
exported. Since it is not always possible to hide them, and two hidden
aliases can share the same entry, the name of hidden aliases are mangled
to '_dispatch_stub_<slot>'.
|
|
Entries with handcode attribute will be handled normally, except no
entry point will be generated for them.
|
|
Split out function name generation from _c_decl to _c_function, and use
it everywhere. Add an optional 'export' argument to _cdecl. It is
prepended to the returned string.
|
|
An entry can hold more info than plain name.
|
|
|
|
Rename MAPI_GLAPI_SOURCES to MAPI_UTIL_SOURCES. Rename macro
MAPI_GLAPI_CURRENT to MAPI_MODE_UTIL. Update the comments to make it
clear that mapi may be used in two ways and how.
|
|
Try not to use macros to make u_current.h appear to be glapi.h. Use
u_current.h to implement glapi.h instead whenever possible.
|
|
TLS requires kernel >= 2.4.20. Per glapi.
|
|
It should be u_thread_self, not _glthread_GetID.
|
|
The preprocessor magic in mapi was nothing but obfuscation. Rewrite
mapi_abi.py to generate real C code.
This commit removes the hack added in
43121f20866bb89e8dac92bd92ec85a943704b7e.
|
|
Right fix is probably stop C-preprocessor abuse and stick 100% with
scripted code generation.
|
|
Fixes nasty bug where some parts of the code didn't define WIN32_THREADS
and were using the integer mutex implementation, causing even confusion
to the debuggers.
And there is little interest of other thread implemenation on Win32
besides Win32 threads.
|
|
Do not use "void *" in arithmetics.
|
|
mapi.h is included by vgapi and st/vega. On win32, the macro expands to
dllexport and dllimport respectively.
|
|
That is, replace the old _glapi_* names by new names that start with
u_current_. When MAPI_GLAPI_CURRENT is defined, u_current.h defines
rename macros to restore the old names. That is done for ABI
compatibility.
|
|
glapi defines an interface that is used by DRI drivers. It must not be
changed in an ABI incompatible way. This commit moves all
functions/variables belong to the interface to glapi.h. Instead of
including u_current.h from glapi.h, u_current.h now includes glapi.h.
|
|
|
|
Define PUBLIC to __declspec(dllexport) when _MVC_VER is defined.
|
|
|
|
|

|
The idea is to have an API generate a header using mapi_abi.py. The API
can then use the header to build a dispatcher.
|
|
Specifically, move all or most of
glapi/glapi.c to mapi/u_current.c,
glapi/glapi_execmem.c to mapi/u_execmem.c,
glapi/glthread.[ch] to mapi/u_thread.[ch]
and remove their dependencies on core Mesa headers.
