[Nouveau] [PATCH] nouveau/codegen: dump tgsi floats as hex values
Printing without this could lead to the following output, while the values are
not exactly zero:
IMM[5] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000}
IMM[6] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000}
IMM[7] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000}
when printing the values as hex, we can now see the differences:
IMM[5] FLT32 {0x00000019, 0x0000000f, 0x00000005, 0x0000001e}
IMM[6] FLT32 {0x0000001e, 0x00000005, 0x0000000a, 0x00000014}
IMM[7] FLT32 {0x00000014, 0x0000000a, 0x0000000f, 0x00000019}

[Nouveau] [PATCH] nouveau/codegen: dump tgsi floats as hex values
This looks like the saner approach, compared to changing tgsi_dump.c to display more fractional digits. Maybe there could be a second option to display as both float and hex?

[Nouveau] [PATCH] nouveau/codegen: dump tgsi floats as hex values
Hi,
yeah in the long run showing both in an ordered manner would be a nice
thing to have! That would include patching the output and the tgsi
parser (who wants to delete half the output to parse it again e.g. with
nouveau_compiler).
I can image an output similar to the one below:
IMM[5] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000} ^ IMM[5] FLT32
{0x00000019, 0x0000000f, 0x00000005, 0x0000001e}
IMM[6] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000} = IMM[6] FLT32
{0x0000001e, 0x00000005, 0x0000000a, 0x00000014}
IMM[7] FLT32 { 0.0000, 0.0000, 0.0000, 0.0000} IMM[7] FLT32
{0x00000014, 0x0000000a, 0x0000000f, 0x00000019}
Greetings,
Tobias
