5 | # These are complicated by the fact we want to build them for guest | |
6 | # systems. This requires knowing what guests we are building and which | |
7 | # ones we have cross-compilers for or docker images with | |
8 | # cross-compilers. | |
9 | # | |
10 | # The tests themselves should be as minimal as possible as | |
11 | # cross-compilers don't always have a large amount of libraries | |
12 | # available. | |
13 | # | |
14 | # We only include the host build system for SRC_PATH and we don't | |
15 | # bother with the common rules.mk. We expect the following: | |
16 | # | |
17 | # CC - the C compiler command | |
18 | # EXTRA_CFLAGS - any extra CFLAGS | |
19 | # BUILD_STATIC - are we building static binaries | |
20 | # | |
21 | # By default all tests are statically compiled but some host systems | |
22 | # may not package static libraries by default. If an external | |
23 | # cross-compiler can only build dynamic libraries the user might need | |
24 | # to make extra efforts to ensure ld.so can link at runtime when the | |
25 | # tests are run. | |
26 | # | |
27 | # We also accept SPEED=slow to enable slower running tests | |
28 | # | |
29 | # We also expect to be in the tests build dir for the FOO-(linux-user|softmmu). | |
