Subject: test/Headers/float.c: fix theoretical edge values
X-Git-Tag: llvmorg-3.9.0-rc1~14279
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14787011156e213d9807c70280c19e62d0215b24;p=platform%2Fupstream%2Fllvm.git

test/Headers/float.c: fix theoretical edge values

For *_MANT_DIG, *_MAX_EXP and *_MIN_EXP, the C Standard does not list
the least requirements directly. This patch adjusts the test values with
refined ones.

Patch by Jorge Teixeira!
