| |
| <p>The ‘<samp>org.gnu.gdb.i386.core</samp>’ feature is required for i386/amd64 |
| targets. It should describe the following registers: |
| </p> |
| <ul class="no-bullet"> |
| <li>- ‘<samp>eax</samp>’ through ‘<samp>edi</samp>’ plus ‘<samp>eip</samp>’ for i386 |
| </li><li>- ‘<samp>rax</samp>’ through ‘<samp>r15</samp>’ plus ‘<samp>rip</samp>’ for amd64 |

| ‘<samp>foseg</samp>’, ‘<samp>fooff</samp>’ and ‘<samp>fop</samp>’ |
| </li></ul> |
| |
| <p>The register sets may be different, depending on the target. |
| </p> |
| <p>The ‘<samp>org.gnu.gdb.i386.sse</samp>’ feature is optional. It should |

| |
| <p>The ‘<samp>org.gnu.gdb.i386.avx</samp>’ feature is optional and requires the |
| ‘<samp>org.gnu.gdb.i386.sse</samp>’ feature. It should |
| describe the upper 128 bits of <small>YMM</small> registers: |
| </p> |
| <ul class="no-bullet"> |

| </li></ul> |
| |
| <p>The ‘<samp>org.gnu.gdb.i386.linux</samp>’ feature is optional. It should |
| describe a single register, ‘<samp>orig_eax</samp>’. |
| </p> |
| <p>The ‘<samp>org.gnu.gdb.i386.avx512</samp>’ feature is optional and requires the |
| ‘<samp>org.gnu.gdb.i386.avx</samp>’ feature. It should |
| describe additional <small>XMM</small> registers: |
| </p> |

| </li></ul> |
| |
| <p>It should describe the upper 128 bits of additional <small>YMM</small> registers: |
| </p> |
| <ul class="no-bullet"> |
| <li>- ‘<samp>ymm16h</samp>’ through ‘<samp>ymm31h</samp>’, only valid for amd64. |
