In addition to the hexadecimal and float (when applicable), print the signed and unsigned representations. Representations may be omitted based on information about the value: - If gather types has unambiguous information, we use it; - Float is omitted for 8 bit values; - Signed decimal is omitted for positive values; - Unsigned decimal is omitted for small values (representation is same as hex); Note for now the "terse form" that appear in SSA uses is unchaged. Based on a patch by Mike Blumenkrantz. Examples: ``` // Just used as float. Omitted decimals. vec4 32 ssa_81 = load_const (0x3f800000, 0x3f800000, 0x3e4ccccd, 0x3f800000) = (1.000000, 1.000000, 0.200000, 1.000000) vec1 32 ssa_28 = load_const (0x3e4ccccd = 0.200000) // Just a small integer. Omitted float and decimal. vec1 32 ssa_45 = load_const (0x00000001) // Larger positive integers. Omitted float. vec1 32 ssa_39 = load_const (0x00002000 = 8192) vec1 32 ssa_30 = load_const (0x000000ff = 255) vec1 32 ssa_28 = load_const (0x00000010 = 16) // Integers with negative values. load_const (0xff = -1 = 255) load_const (0xff80 = -128 = 65408) load_const (0xffff = -1 = 65535) // Same value, in the first case we know is used as an integer. load_const (0xffffffe0 = -32 = 4294967264) load_const (0xffffffe0 = -nan = -32 = 4294967264) ``` Reviewed-by: Jesse Natalie <jenatali@microsoft.com> Acked-by: Emma Anholt <emma@anholt.net> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/23562>

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question.
