I propose adding the following global USE flag: |
| 2 |
|
| 3 |
jit - Enable just-in-time compilation for improved performance. May |
| 4 |
prevent use of some PaX memory protection features in Gentoo Hardened. |
| 5 |
|
| 6 |
|
| 7 |
Current local flags that could probably be unified: |
| 8 |
|
| 9 |
app-arch/libzpaq:jit - Enable just-in-time compilation for faster |
| 10 |
compression (requires SSE2) |
| 11 |
|
| 12 |
dev-libs/libpcre:jit - Enable Just-In-Time compilation of regexp |
| 13 |
bytecode to machine code, through the SLJIT compiler. This feature might |
| 14 |
conflict wtih security mitigation strategies such as NX/PaX as enabled |
| 15 |
by Gentoo Hardened. |
| 16 |
|
| 17 |
dev-python/pypy:jit - Enable the JIT compiler |
| 18 |
|
| 19 |
dev-scheme/racket:jit - Enable just-in-time compiler |
| 20 |
|
| 21 |
media-sound/csound:luajit - Use the lua just-in-time compiler |
| 22 |
dev-lang/luajit instead of dev-lang/lua |
| 23 |
|
| 24 |
net-libs/webkit-gtk:jit - Enable JIT javascript compiler (disabling it |
| 25 |
will cause performance penalty) |
| 26 |
|
| 27 |
www-client/epiphany:jit - Allow using net-libs/webkit-gtk that has the |
| 28 |
JIT javascript compiler enabled |
| 29 |
|
| 30 |
www-client/luakit:luajit - Use the lua just-in-time compiler |
| 31 |
dev-lang/luajit instead of dev-lang/lua, which should make luakit |
| 32 |
faster. |
| 33 |
|
| 34 |
www-client/seamonkey:methodjit - Enable JIT for JavaScript using |
| 35 |
MethodJIT for faster JS performance. Hardened users can disable this |
| 36 |
USE-flag to use MPROTECT on grsecurity kernels. |
| 37 |
|
| 38 |
www-servers/nginx:pcre-jit - Enable JIT for pcre |
| 39 |
|
| 40 |
x11-libs/qt-core:jit - Enables JIT for Javascript usage inside Qt |
| 41 |
|
| 42 |
x11-libs/qt-script:jit - Enables JIT for Javascript usage inside Qt |
| 43 |
|
| 44 |
x11-libs/qt-webkit:jit - Enable JavaScriptCore just-in-time compiler for |
| 45 |
faster JavaScript execution |
| 46 |
