J is the flag passed to make. Default is empty string.
|

|
|
|
| 51 |
|
|
STANDBY is the number of minutes between checks for new patches in
|
| 52 |
|
|
PATCHES_DIR. Default is ${default_standby} minutes.
|
| 53 |
|
|
|
| 54 |
|
|
WATERMARK is the 5 minute average system charge under which a new
|
| 55 |
|
|
compile can start. Default is ${default_watermark}.
|
| 56 |
|
|
|
| 57 |
|
|
SAVECOMPILERS copies the compilers in the same directory as the
|
| 58 |
|
|
test results for the non patched version. Default is not copy.
|
| 59 |
|
|
|
| 60 |
|
|
NOPRISTINECACHE prevents use of cached test results from any earlier
|
| 61 |
|
|
test runs on the pristine version of the branch and revision under
|
| 62 |
|
|
test (the default behaviour). This should be used when testing the
|
| 63 |
|
|
same revision and patch with multiple sets of configure options, as
|
| 64 |
|
|
these may affect the set of baseline failures.
|
| 65 |
|
|
|
| 66 |
|
|
NOGPG can be used to avoid checking the GPG signature of patches.
|
| 67 |
|
|
|
| 68 |
|
|
URL is the location of the GCC SVN repository. The default is
|
| 69 |
|
|
${svnpath}.
|
| 70 |
|
|
|
| 71 |
|
|
STOP exits when PATCHES_DIR is empty.
|
| 72 |
|
|
|
| 73 |
|
|
SOURCE_DIR is the directory containing GCC's toplevel configure.
|
| 74 |
|
|
|
| 75 |
|
|
PATCHES_DIR is the directory containing the patches to be tested.
|
| 76 |
|
|
Default is SOURCE_DIR/patches.
|
| 77 |
|
|
|
| 78 |
|
|
STATE_DIR is where the tester maintains its internal state.
|
| 79 |
|
|
Default is SOURCE_DIR/state.
|
| 80 |
|
|
|
| 81 |
|
|
BUILD_DIR is the build tree, a temporary directory that this
|
| 82 |
|
|
script will delete and recreate. Default is SOURCE_DIR/obj.
